Personal- personal hygiene, teamwork, friendly and willing to interact with customers, smile!
Restaurant Service
Plated- The most common type of table service where the main part of the meal is plated and vegetables are served in a creative way.
Family- The most suitable for ethnic restaurants where people often share a range of dishes. Food is put on the table and customers help themselves.
Silver- The most traditional style of service and is usually found in the dining restaurants and hotels. Guéridon service can be part of this style of dining, where some dishes are cooked in front of the customer.
Food Service
Customer Needs
Customers have expectations that their needs, such as a comfortable bed, plenty of hot water and a tasty meal, will be met. Customer satisfaction is created by meeting needs.
The five main customer expectations are:
Value for money- They must feel that the price paid for goods and services is fair. This does not always mean cheap.
Accuracy and reliability- The service or goods promised should be delivered as expected.
Information, advice and help- Customers expect that they will be given information and advice before they even ask for it. Eg. Expect a waiter to explain the menu.
Problems and complaints dealt with correctly- Staff must sort problems as quickly and correctly.
Health, safety and security- There is a duty of care towards customers within an establishment to keep the customers safe and secure.
Customer Service
Communication & Record-keeping
Good communication is essential in the catering industry as it is a ‘service industry’.
Different types of communication:
Verbal Non-verbal- unspoken for example body
language. Written Telephone Fax Internet-Internet, email, web.
Different types of communication are needed in different circumstances. E.g. some customers may have communication difficulties- partially sighted or blind, deaf or hard of hearing.
The main purpose of staff employed in the industry is to look after customers’ needs. Good communication= a successful business and happy customers.
Good communication is a combination of:
Observing-Watching customers and offering them help and advice.
Listening- Listening carefully to what is being said.
Thinking- Thinking carefully about what to say to using easy to understand language, not jargon.
Knowing- What the establishment offers. Describing- Describing items on menu and
the services provided by the establishment. Suggesting- E.g. wine, food, alternatives.
Uses of ICT in the industry: Reservation systems- A
customer can ring or email a central reservation number/email address and a room can be booked for any hotel in the group.
Management system- Room reservation, guest billing, guest history.
Electronic point of sale (EPOS)- A number of machines are linked to a central computer. Guests can order from the bar, restaurant or shop. All transactions are passed through a central computer for bills to be generated automatically.
Uses of ICT in the industry 2:
Stock control system- These hold details of suppliers. They generate orders automatically when stock level fall.
Food and beverage management systems- A database of recipes, quantities needed , ingredients codes etc.
Events management- Used when planning, organising and running large events. Data from one event can be saved and used for similar future events.
Dietary analysis programs- Nutritional analysis of menus, recipes and ingredients.
Record-KeepingIt is very important to keep accurate, appropriate records. The types of records used are:
• Stock control sheets• Invoices• Staff rotas• Food and drink orders• Restaurant bookings• Details of accidents.
Setting a Table for Lunch and Dinner
Setting up a table for lunch or dinner depends on the type of menu being served.
The basic two type of menu served are:
-a la carte
-table d’ hote.
For À la Carte Menu:À la carte refers to individually priced dishes placed on an extensive menu. This way, there is more of a choice but the ingredients are more extravagant and therefore the price is higher. This a table setting normally laid in a high class restaurant, dining room or hotel in readiness for served of either lunch or dinner. It would consist of the following:Fish PlateNapkinFish knifeFish forkSide plateSide knifeWater or wine glass.
For À la Carte Menu:
Table d’ hôte Menu:This literally means in French, ‘the host’s table’ but in menu planning terms, means a fixed price menu. Cooking methods tend to focus on heartier methods, for example, braising a joint of beef. The table would consist of the following:
Napkin
Soup spoon
Fish knife
Fish fork
Water or wine glass
Sweet spoon
Sweet fork
Side plate
Side knife
Table d’ hote Menu:
Laying the table with cutlery / flatware To use the right cutlery or flatware and set the table
properly with the correct knives and forks is not really difficult and when you sit down to eat just remember to start from the outside and work inwards. The idea should never be to intimidate your guests, instead you will put them at their ease.
Setting the table properly makes life easier for the guest. They will see a table which looks good and feel, quite rightly, that you are making them feel welcome. A well laid table speaks volumes to a guest.

• Left is a picture of a place setting .
• (This particular design is called Windsor. This is a plain, simple yet stylish cutlery design.)
• This table is set for soup, a main course and a dessert.
• A small butter knife has been placed on a small plate to the left of the place setting. This could be used for bread rolls or later for the cheese course.
The diagram below shows the layout of a table set to include a fish course. On the far right is a soup
spoon. Then from the outside to the inside this illustration shows: fish knife and fork, dinner ( or table) knife and fork, dessert knife.
Above the dinner plate is a dessert fork and dessert spoon.
Glasses may be in a triangle or a straight line and napkin on the bread which should already be on the plate.
Hand Blender
Domestic hand blenders can be used to blend small amounts of soups and sauces. However, when blending large catering quantities, a specialist industrial hand blender is required.
Liquidisers
The same rule applies for liquidisers. When the number of customers increases, the size and the sturdiness of the equipment must increase also. They also blend small amounts of soups and sauces.
Food Processors
They have multiple applications, including chopping, slicing, liquidising etc. They have separate attachments to do each task. Food processors are best used for large quantities.
Mixing Machines
They use a whisk attachment or a dough hook. They make pastry and bread dough and meringues on a large scale. Attachments can also be added to mince or blend.
Equipment:
Guéridon TrolleyAlso known as a flambé trolley. It is a portable waiter/waitress station used for cooking the finishing of flambé items. For example in the preperation of crêpe Suzette the pancakes would already be made but the person making the pancakes would make the suzette sauce, heat the pancakes in the sauce and serve directly to the customers at the table
Coffee, Espresso and Cappuccino MachinesThey filter the coffee through and water is dripped through.
Food Display UnitCan be kept at either ambient temperature (room temp) or chilled (same temp as fridge below 5°C).
Large Equipment:
SalamanderOther name for grill
Griddle unitThis unit is like a grill but doesn’t require open flames.
Bain-MarieA container of water used to keep foods hot without fear of burning or to cook delicate foods.
OvensInduction hob- Uses electromagnetic induction to heat a pan (ceramic hob). They are hotter.Convection oven- Fan assisted transferring heat around the oven.
Other Equipment:
Palette knifeA small, flat knife with no edges used to pick items up.
MandolinA professional slicing instrument with adjustable blades used to cut up vegetables.
Special cutter- Parisienne cutter (scoop)Otherwise known as a melon baller. Used to cut small spheres out of food Eg. Melon.
SpatulaA plastic utensil used to scrape the last ingredients out of the bowl.
Small Equipment:
Knives Used in Industry
A cooks knife (for chopping)
A filleting knife (for fish)
A boning knife (for meat)
A palette knife for lifting, scraping and mixing
A steel (for keeping knives sharp)
A small paring or vegetable knife (for peeling and cutting small foods)
A peeler (for peeling fruit and veg)
1. Use the correct knife for the job
2. Knives must always be sharp and clean
3. Handles must be free from grease
4. Points must be held downwards
5. Knives should be placed on a flat surface so that the blade is not exposed upwards
6. Knives should be wiped clean with the edge away from the hands
7. Do not put knives into a washing ups sink
Knife Safety
• A balanced diet contains a wide variety of foods
• Food contains a mixture of different nutrients which have different functions in the body.
• A healthy diet will provide adequate amounts of all nutrients needed by the body for good health.
Nutrition & Menu Planning
Foods containing… protein carbohydrate fat…provide the body with energy.
Food also provides…
• fibre;• water;• vitamins and minerals.
These substances do not provide the body with energy, but are all needed to fulfil some important ‘support’ functions for the body.
Nutrition & Menu Planning
The Balance of Good Health is based on five food groups which are:
Fruit and vegetables Bread, other cereals and potatoes
Meat, fish and alternatives
Milk and dairy foods
Foods containing fat
Foods containing sugar
Nutrition:The Eatwell Plate
Fruit and Vegetables
•Aim for at least 5 portions a day.
•Fresh, dried, frozen, canned and juiced - they all count.
Main nutrients: carotene (in carrots), vitamin C, folates and fibre. Vit C needed for immune system and to prevent scurvey, fibre to prevent constipation and bowel cancer.
Nutrition:The Eatwell Plate
Bread, other cereals
and potatoes
•Eat plenty of foods rich in starch and fibre.
•Fill-up on wholemeal bread, potatoes, rice, pasta and yams.
Main nutrients: carbohydrate (starch), some calcium and iron, vitamin B, and fibre. Carbohydrate and starch needed for slow release energy. Fibre (NSP) needed to aid digestion to prevent bowel cancer. Vitamin E in cereals, nuts and oil helps growth of body and to develop red blood cells
Nutrition:The Eatwell Plate
Meat, fish and alternatives
•Help the body to grow and stay healthy.
•Eat a range of meat, fish eggs, nuts, seeds, tofu, beans, and pulses.
Main nutrients: iron, protein, B vitamins (B12), zinc, magnesium
Protein and iron help the body to grow and stay healthy.
Vitamin A helps eye sight and overall health, found in liver and eggs
Nutrition:The Eatwell Plate
Milk and dairy foods
•Help bones and teeth to grow strong and stay healthy.
•Try lower-fat options.
Main nutrients: calcium, protein, vitamin B12, vitamins A & D
Protein is needed for growth and repair and calcium for strong bones, Vit A&D also needed for strong bones as well as skin and eyes.
Nutrition:The Eatwell Plate
Foods containing fat /
Foods containing sugar
•Don’t eat too many foods that contain a lot of fat. Leads to obesity.
•Don’t have sugary foods and drinks too often.
•Leads to tooth decay.
Nutrition:The Eatwell Plate
Target Group Requires
Baby Breast milk which contains special proteins, antibodies and white blood cells which help to protect the baby against infection. It also contains a substance to help the baby grow.
Children Foods that are high in energy as they grow quickly. Calcium is needed for healthy tooth development and, vitamin D, helps make bones stronger.
Teenager Calcium for bones (teenagers have growth spurts). Girls and boys differ in how much they need; boys need more protein and energy than girls due to their greater growth spurt. Girls need more iron than boys once their periods start.
Adult Plenty of starchy foods and fruit and vegetables, meat or its alternatives, milk and only small amounts of foods and drinks containing fat and sugar.
Older Adult Vitamin B to help release energy and Vitamin C to help fight infection
Types of vegetariansThere are three main categories of vegetarians:1.Vegans do not eat the flesh of any animal (no meat, poultry or fish) and no eggs, milk, cheese, honey etc.2.Lacto-vegetarians do not eat the flesh of any animal (no meat, poultry or fish) but they do eat eggs, milk, cheese.3.Semi vegetarians often choose to eat a mainly vegetarian diet because they don’t eat red meat. They sometimes do eat white meat (poultry and fish) and eggs, milk, cheese etc.
Some people choose not to eat certain foods. There can be a variety of reasons for this:
Because of their ethnic beliefs. Because of their religious beliefs. For medical reasons. They do not like the taste or texture of
some foods.
A vegetarian diet is considered healthy because of the emphasis…on fresh fruit and vegetables. Protein is obtained mainly from beans, lentils, peas, nuts and wholegrain cereals, which are also rich in vitamins and minerals.
There are many reasons why people chose a vegetarian diet:
They may have strong feelings about the way animals are kept and slaughtered.
Land used to feed animals could feed many more if it was used as crops.
Many cases of food poisoning are linked to meat. A vegetarian diet is considered to
be healthier (lower in fat and cholesterol, higher in fibre) than one that relies on meat.
Menu Planning Government Guidelines: eat less fat, less sugar, salt, alcohol and eat more fibre should be considered in menu planning to provide a balance of dishes.
Menus should be a balance of different starters, mains, desserts – not repetitive in terms of types of dishes e.g. fish, meat, poultry
(chicken, turkey, duck), vegetarian, dishes suitable for those
dieting, people who can’t eat milk products (lactose intolerance)
or wheat, consider religious and cultural implications.
Colour, texture and value for money must also be considered when presenting a menu. It must be presented correctly and in a attractive and appealing manner to the consumer.
Before you start planning a menu, consider the 4W’s:
WHO is going to eat the food (age, sex, occupation, specific dietary needs)?
WHEN is it going to be eaten (time of year, time of day)?
WHERE is it going to be served/eaten (venue, space and facilities available)?
WHAT type of food is going to be eaten (sit down meal, buffet, breakfast, lunch, dinner, special occasion)?
Other points to consider:
Nutritional needs, including specific dietary needs. Time of year Weather Types of customer Time available Price Portion control Ability of the cook Ability of the waiting staff Equipment available (for preparation, serving, cooking) Balance (colour, flavour, texture, shape, variety of ingredients) Presentation
Planning a good menu. Tips-
Children's menus- should be fun and include healthy alternatives to children's favourites. E.g. potato wedges instead of chips. Children could have more choice by offering smaller portions of main meal dishes from the adult menu.
Specials- Many restaurants have ‘specials boards’, which is a good way of adding seasonal dishes to the menu.
Breakfast-Even simple breakfasts should offer a choice of hot (bacon, egg, sausage, tomato etc.) and cold continental (rolls, croissants, cheese, cold meats, etc.) Hot and cold drinks and a tasty selection of preserves should be offered.
Planning a good menu. Tips-
Lunch- Often needs to be served quickly for customers who have limited time.
Sandwiches, wraps and baguettes are ideal. An ideal menu will offer a variety of breads with a selection of hot and cold fillings, together with snack items such as jacket potatoes, salads, pastries, cakes and muffins.
Evening meal- Vegetarian and healthy choices should be offered as well as dishes using a variety of cooking methods.
In the UK, the most popular menus offer hot and cold starters, a variety of main courses and a selection of desserts that include chocolate and fruit.
Choosing a menu
Decide on the main course ‘protein items’ first, for example chicken breast, pork fillet, lamb cutlets, liver, cod, salmon, tuna, quorn, tofu and cheese.
Decide on the desserts-these should ‘balance’ the protein items for colour, flavour, texture and nutrients.
Choose the vegetables- these should ‘balance’ the other dishes chosen, especially regarding colour
Choose the starters.
Types of menu Table d’hôte or set-price menu- a fixed or set-price
menu with a limited selection of dishes for every course. A la carte menu- all dishes are individually priced. Party or function menu- Usually a fixed-price menu
offered for parties or functions such as wedding receptions. Some party's menus offer a limited choice.
Ethnic or speciality menu- Can be fixed price or á la carte. Some offer dishes from particular countries. E.g. China, Italy. others offer specialised food, e.g. fish or vegetarian dishes.
Fast-food menu- This is similar to a speciality menu. Food tends to have ‘themes’ such as burgers, chicken or baked potatoes. Items are priced individually.
Rotating menu cycle- Often used in primary schools. A fixed pattern of menus is used to cover a fixed number of days. The minimum number of days is eight, so that menus are never repeated on the same day each week.
Commodities:Considerations when selecting & storing:
Vegetables & FruitChoose fruits & vegetables in season for the best quality. Check for bruising and signs of mould. Check fruit is ripe or a little under ripe, not over ripe so it is wasted. Should be stored in a dry cool area, carefully so that it does not become damaged. Not near smelly food so it becomes tainted.
Meat & PoultryMeat should be kept in the fridge, raw meat should be kept away from cooked meat. It should be used by the specified date and be in good condition, not bruised.
FishOily fish – salmon, trout, tuna should beWhite flat – Lemon sole, halibut bright eyes,Round – Bass, cod, hake not slimy or smelly.
Nutrition & Menu Planning
Commodities:Considerations when selecting & storing:
EggsCome in 4 sizes depending on size & graded A to C for quality. Eggs have to have use by dates and quality control to prevent salmonella. Should be stored in a cool dry place or fridge, away from raw meat, hands should be washed before & after handling, don’t use cracked eggs.
DairyDairy products have to be kept in the fridge and must be used within use by dates. Milk & cream should always be kept in the container in which it was delivered. Cheese is best served after it has been taken out of the fridge and allowed to reach room temperature.
Dry goods Should be kept in a cool, dry place off the ground.
Cook-chill foods Kept in the fridge & reheated thoroughly. Before use by date.
Canned foods must be kept in a cool place, used on rotation before use by date.
Convenience (partly prepared foods) can be use along side fresh foods to make for more efficient and more quickly prepared dishes.
Nutrition & Menu Planning
It is vital to cost dishes accurately to make a reasonable profit. Portion control
(keeping the size of a portion the same every time by using the same size container or serving spoon).
The total cost of a food item depends upon 3 things:1. Food or materials cost the cost of the raw materials or
ingredients. 2. Labour costs - Direct labour cost e.g. the wages of the chefs,
Indirect Labour costs - other people who work in the restaurant.3. Overheads - the cost of rent, rates, heating, lighting, electricity,
gas.
Sales - Food Cost = Gross ProfitSales - total cost = Net ProfitFood cost + Gross Profit = Sales
Gross Profit is usually around 40%Net Profit (after Labour & overheads have been taken out) is
around 20%
Costing
Portion Control
Portion control is extremely important. Customers need to feel they are getting ‘value for money’ and having the same size portion as everyone else. It helps the caterer when planning (how many portions will these ingredients make?) considering selling price (how much should I charge to cover costs and make a profit?) and avoids waste.
Using standard recipes can help a caterer by determining how many ingredients will make 10, 20, 30 or more portions.
Using standard size dishes will also help.
Gateau Recipe £ p
3 eggs 0. 4575g caster sugar 0. 0975g flour 0. 03250ml double cream 0. 75small punnet of strawberries 1. 99
Total cost 3. 31
Once you have the total price of the gateau you need to calculate the price per portion.
The gateau made 8 portions therefore the price of 1 portion is total price ÷ 8.
The gateau cost £3.31 for 8 portions therefore 1 portion costs £3.31 ÷ 8.
This works out at 42 pence per portion (to the nearest p)
Costing
The ‘selling price’ of food is calculated (worked out) according to the amount of profit that an establishment wants to make.
This is because the selling price has to take into account: The actual food cost (the cost of the ingredients) Overheads (the cost of rates, gas, electricity, etc.) Labour cost (staff wages) Profit
The mathematical formula used in the Catering industry is:
Food cost x 100 ÷ 40
This would give a 60% gross profit to cover profit overheads and labour.
A simple way of working out the selling price is to multiply the food costs by 3.
Example: food costs £2.50suggested selling price would be £2.50 x 3 = £7.50.

Measuring Weighing Following a recipe accurately Thorough preparation Use of correct techniques e.g. Sieving,
whisking Accurate shaping e.g. Cutters and
moulds Correcting errors
Key Words
Quality Control – using checks to ensure the product is made to a high standard e.g. Sensory checks, measuring depth and width, checking quantities like the number of slices of pepperoni on a pizza, checking toppings are evenly spread etc
Consistent - the same standard e.g. The size of a frozen pizza has to be consistent, partly to keep customers happy and maintain good value for money, partly so that it will fit in the box.
Proportion – the ratio of ingredients e.g. 50g of flour, margarine and sugar to 1 egg using the all in one cake making method.
Technique - way of doing something e.g. Rubbing –in, whisking
Tolerance - an agreed allowance for a quality target e.g. The cake should be 5cm deep + / - 20mm
Food Presentation:Meals must be presented with the consideration of:
1. The importance of colour, texture, flavour, shape, temperature and time.
2. The customers needs/situation/occasion/types of menu.3. An appropriate eating environment.4. A wide range of culinary skills.
Customer complaints must be dealt with immediately:
1. Apologise and remove the offending item.2. Offer a replacement or substitute.3. Inform the kitchen of the problem.4. Provide the replacement or substitute ASAP.5. Offer a free dessert or tea or coffee.6. Do not charge for the item that had to be replaced.7. Inform management.
What are smart foods?Smart foods are those that have been developed through the invention of new or improved processes, for example, as a result of man-made materials/ingredients or human intervention; in other words, not naturally occurring changes.
Smart foods may: have a function, other than that of providing energy and nutrients; perform a particular function never achieved by conventional foods; have been developed for specialised applications, but some eventually become available for general use.
Smart Foods?
1. Modified starches.
2. Functional foods, e.g. cholesterol lowering spreads, probiotic yogurts, fortified eggs.
3. Meat analogues, e.g. textured vegetable protein (TVP), myco-protein and tofu.
4. Encapsulation technology, e.g. encapsulated flavours in confectionery
5. Modern biotechnology, e.g. soy bean, tomato plant, modified enzymes, e.g. chymosin.
Smart foods include:
Myco-protein is used in fillets to provide a ‘chicken like’ texture.
Tofu absorbs flavours, so is used as a meat alternative in stir-fries.
TVP is used in vegetarian shepherd’s pie to provide the main source of protein.
Ingredients that mimic the organoleptic properties of meat.
Meat Analogues
Potatoes can be altered to reduce the absorption of fat during frying.
Maize is modified to control pests, minimising crop damage.
Chymosin, a modified enzyme, is used to produce ‘vegetarian’ cheese.
Specific changes to a plant or animal at a genetic level.
Genetically Modified Foods
Jellybeans use encapsulated flavours for enhanced sensory appeal.
Specially formulated ‘sports’ bars are fortified with encapsulated nutrients.
Some breads use encapsulated leavening agents to prevent premature release and reaction.
The coating of a particle with an outer shell.
Encapsulation Technology
Some eggs contain Omega-3 fatty acids, known to benefit heart health.
Specially formulated spreads help to lower cholesterol levels in the body.
Probiotic drinks are designed to improve the health of the large bowel.
Foods that contain an ingredient that gives health promoting properties.
Functional Foods
The noodles in ‘pot snacks’ are pre-gelatinised, so boiled water will re-heat and
'cook' them.
Modified starch is used in ‘cup-a-soups’ to improve mouth-feel, thicken the drink/sauce with the addition of boiled water, and blend uniformly with no lumps.
Starches that have been altered to perform additional functions..
Modified Starches:
Modified Starch
Starches that have been altered to perform additional functions..
Modified starch is used as a fat replacer in low-fat meals.
To prevent ‘drip’ after a pie is defrosted, modified starch is used in the sauce.
Pre-gelatinised starch is used to thicken instant desserts without heat.
Modified Starches:
Restaurants use many different types of marketing to encourage consumers to choose their product:
1. Promotions
2. Advertising
3. Direct Mail
4. Merchandising – displaying products appealingly
Packaging Materials:
Different materials are used for different purposes:
1. Biodegradable 5. Aluminium Foil
2. Recycled 6. Cardboard & oven proof
3. Vacuum packed (the air removed) paperboard.
4. Cling film 7. Plastics
Marketing Techniques:
The most valuable thing for any business is up to date information. Therefore computers are vital. They can be used for:
1. Computer Operations software packages used for Point of Sales (tills), and management systems. Used for stock control, pricings, ordering, accounts can be kept more accurately etc.
2. Menu Design and Nutritional Analysis
3. Internet to keep up to date and monitor competitors, marketing of the restaurant on a website.
4. Keeping customer details
5. Keeps information securely and reduces the amount of paper

Optional information may include..• Processing aids & any solvent/carrier used only for technical reasons• GM - Only approved GM foods may be sold and if a food contains any GM ingredients, this must be
shown on the label• Labelling regulations require any food containing novel GM material (the DNA that has been altered
or the proteins that the DNA produces) to be labelled• Highly processed food ingredients (such as refined vegetable oils) that are produced from a
genetically modified source but that no longer contain any GM DNA or protein, currently do not have to be labelled because they are indistinguishable from those produced from non- GM sources.
• Small amounts (below 1%) of GM material that are accidentally present in non GM ingredients do not have to be labelled

Repair
Nutrient Why we need it Too much /not enough?
Protein To build and repair muscle Too much: Is used for energy or stored as fat
Fats To keep us warm and to help absorb some vitamins
Can cause obesity, stroke or coronary heart disease
Carbohydrates To give us fuel for energy, keep us going. 2 types, sugars and starches.
Can cause obesity if not burned off because they are stored as fat. Too much sugar can also cause dental decay
Vitamins A = Healthy Eyes and Bones B = Releases energy from foodC = Helps us absorb iron D= Strong teeth and bones
Not enough can causeA: vision problems, dry skinB: beri beriC: scurvy / slow healingD: rickets / osteoporosis
Minerals Calcium – strong bones / teeth & bloodIron – transports oxygen round body

Banana
At home, fruit is stored in a fruit bowl but in a hotel, to stop deterioration it is stored in a refrigerator. Bananas should be kept at room temperature and separate from other fruits to stop them from bruising.
Decorative PreparationsFanningFruits such as strawberries or melon can be cut using a knife to create a afnned effect.Van DykeUsing a knife or a specialist tool, a V shape is cut around the circumference of melon, for example, to create a tooth effect.
Boiling- Bring the liquid to 100°C. This turns the fluid into vapour, which reduces any volume in the pan. A variety of meats, fish poultry and vegetables can be boiled.
Blanching- There are a number of different uses for blanching, such as, to par cook or to remove the skin from vegetables.
Par cooking- Partly cooking food. In a hotel, it is sensible to par cook vegetables precisely the right degree and cooled, drained and presented ready for a function later on that day.
Removing the skin- From tomatoes, remove the core from the base of the tomato, place a criss-cross on the top of the tomato (to help remove it) and then place the tomatoes into the boiling water for approximately 10 seconds. Then place the tomato into very cold water until cool. Then skin then can be easily removed.
Steaming- This makes sure that vitamins and minerals are not lost. The vegetables are elevated above the bubbling water. It is not touching it.
Poaching- A slow and gentle method of cooking used for vegetables, meat, fish, poultry or egg. It cooks the food in simmering water.
Cooking Techniques
Braising- A combination of moist and dry heat whereby a piece of meat is first sealed in hot fat and then cooked slowly in a sauce or stock for a long time until tender.
Stewing- Is similar to braising, except the pieces of meat or poultry are quite small and the liquid is served with the dish. It can be done on top of the oven in a pan, or in a casserole dish in the main oven.
Deep Frying-Using a temperature controlled deep-fryer (with adjustable basket) is far safer than a pan filled with oil over an open heat. This method is used to cook most items including goujons of fish, meat samosas and even deep-fried ice-cream.
Shallow Frying- Cooking a product in a small amount of hot oil in a shallow pan over an open heat.
Baking- Dry heat without any oil or fat, which can be done in an oven. The air is forced around to create a more even distribution of heat and a more consistent end result.
Roasting- In a pot in the oven (pot roasting) or rotating over a centre spit over a naked flame.
Cooking Techniques
Freezing Freezing is the most common
method of food preservation as it allows food to be stored for longer periods.
The drawback is if there is a power failure – all the food will spoil.
It is important to follow the manufacturer’s instructions as incorrect freezing will damaged (rupture) cells and result in loss of nutrient value.
Long periods of storage will also result in nutrient loss.
Preserving Food
Smoking
This method is great for meat.
Meat that is smoked retains most of the nutrients and the taste is delicious.
Dehydrating or drying food
Drying is excellent for most fruits and vegetables.
When you dry a food you take out the water or moisture from it and this prevents spoilage.
The advantages are that the dried product weighs very little and the size is reduced for easy storage.
The food retains almost all of its nutrients.
There are several ways to dry food: sun-drying, oven-drying and drying in a dehydrator.
The first two methods are difficult.
Canning
You can preserve raisins, coconut, grains, beans, any kind of dried fruit or vegetable, pasta, rice or legumes.
Anything dry will be good for this method of preservation.
The science of heat
Cooking is the transfer of heat energy from a source to the food.
In the kitchen there are three devices that are used to cook food: the hob conventional oven microwave oven.
Each of these devices are designed around a different method of heat transfer.
Other methods of food preservation
Vacuum packing This is where food is stored in an airless environment. The vacuum means that bacteria cannot reproduce. This is a good preservation method for nuts.
Salting This is also called curing. The salt draws moisture from the food through
osmosis. The lack of moisture increases the amount of time
before the food spoils

Other methods of food preservation
Pickling This is preserving food in a liquid that has anti-
microbial properties, such as vinegar. There are two types of pickling; chemical and
fermentation. In chemical pickling foods are placed in liquids such
as vinegar, brine, or alcohol in order to preserve them, e.g. onions or eggs.
In fermentation pickling the food 'ferments' and creates the preservation agent, such as lactic acid.
An example of this would be sauerkraut.

Heat transfer
Convection
Conduction
Radiation
Convection
Convection is heat transfer through a fluid.
The fluid can be liquid or gas and in the case of a convection oven, the fluid is air.
© Folens 2009
Conduction
Conduction is heat transfer through direct contact.
When cooking on the hob, the heat from the flame is applied directly to the pan.
This means that only the flat surface of the pan is sufficiently hot enough to cook anything and we must flip and toss around the food to cook it properly.
Heat energy from the hob is transferred to the saucepan by conduction.
© Folens 2009
Radiation
An example of cooking with radiation is using a microwave.
Microwave ovens work by spinning water, fats, sugars and oils inside the food.
This causes friction, which then heats the food and cooks it from the inside.

(HASAWA) Health & Safety at Work Act 1974The law means that employers must ensure the health, safety and welfare of staff. It also states that staff (employees) must:
1. Take care of their own health, safety and welfare and other persons that they work with.
2. Co-operate with the employer to comply with all health & safety matters.
3. Not interfere with or misuse anything provided in the interests of health, safety and welfare.
Employers must ensure they provide safe premises, equipment, provide supervision and training, have a written safety policy and consult with unions and have a safety committee.
Safety At Work
The major causes of accidents in the catering industry are due to:
Slips, trips, lifting heavy or sharp objects, exposure to hazardous substances, hot surfaces
& steam. Struck by moving articles including hand tools, walking into objects, machinery (slicers, mixers etc), falls, fire & explosion, electric shock and fork lift trucks.
Accident Prevention:
It is essential that people are capable and trained in using tools and are aware of the possible accidents. That people are not rushed or distracted. Everyone is responsible to observe safety rules, accidents should be recorded in a book or on a form.
The Catering Industry
Since 1982 it has been a legal requirement that adequate first aid equipment and personnel are provided at work. If an injury is serious they should be treated by a doctor or nurse or an ambulance called.
First Aid boxes must be easily identified and accessible and checked regularly.
Cuts: covered immediately with a waterproof blue dressing. Direct pressure may be applied to stop heavy bleeding.
Burns (dry heat) & Scalds (wet): Place under slowly running or in a bowl of cold water until the pain ceases. If serious the burn should be covered with a sterile dressing and the person sent to hospital. Do not apply any creams, do not cover with a plaster.
First Aid:
Fires need 3 things to burn so if you take one of these away the fire does not happen or is put out:
1. Fuel – something to burn
2. Air – oxygen to keep the fire going
3. Heat – gas, electricity etc
Methods of extinguishing fires:
1. Starving – removing the fuel
2. Smothering – removing the oxygen
3. Cooling – removing the heat.

What is Food Hygiene?
It’s purpose is to preserve health by:
• Reducing the risk of producing harmful food
• Preventing infestations by pests like flies, mice
Poor hygiene can also lead to:
• Food wastage
• Infestation by pests
• Loss of customers and profit
• Legal action against you or the firm you work for
The good practices which lead to clean workplaces and the safe production of food
What does it involve?
Personal Hygiene Cleaning and disinfecting Preventing any organisms multiplying Destroying any harmful bacteria by cooking Discarding unfit or contaminated food
Food poisoning is more likely to affect people with lowered resistance to disease than healthy people who might show mild symptoms or none at all.
The following are particularly vulnerable to food poisoning: -
• Elderly or sick people
• Babies
• Young children
• Pregnant women
Vulnerable Groups
Physical – Rodents, insects, dust, paper, machine parts, food bones, shell, hair, jewellery
etc
Chemical – Cleaning chemicals, pesticides
Microbial – Food poisoning bacteria(Biological) Most common cause
Contamination
In order to grow and multiply germs need:
WarmthFood(Particularly high-risk
foods)
MoistureTime
Remember it like this…
Too Many Flies Waiting
High-risk foods Cooked meats and poultry Raw meat and poultry Cooked meat products such as pies, gravys made by meat stock Meat and fish patés Lightly cooked milk and egg products such as mousse and mayonnaise Shellfish and seafood Cooked rice
They must be handled with care:1.Don’t use after the use-by date.2.Transport in a cool temperature.3.Store covered in fridge and separate from other foods.4.Prepare on separate coloured chopping board.
Correct use of boards for food preparation, in order to avoid cross-contamination.
White- Bakery & Dairy Products
Red- Raw Meat
Blue- Raw Fish
Green- Salad & Fruits
Yellow- Cooked Meats
Brown- Raw Vegetables
Coloured Chopping Boards
In ideal conditions where there is Moisture, Food and Warmth (37degrees centigrade is ideal), bacteria can double every 10 to 20 minutes (in Time). They do this by dividing in to two.
This is called…

Knife contaminated by blood
cooking chicken to a core temperature of 75°C should kill most of the bacteria
Spore: This is a protective coating around the bacteria. This prevents it from getting killed in normal cooking and have to be heated at very high teperatures.
Toxins
Some bacteria release poisons known as toxins which cause food poisoning. Some toxins, known as exotoxins multiply in food. These toxins are not easily destroyed by cooking and may remain in food once they have developed. Other bacteria produce toxins inside the human body only after the food has been eaten. These are called endotoxins
Types of bacteriaSpoilage: Not
particularly harmful bacteria which cause food to go off
Beneficial: “Good Bacteria” which are used to make yoghurt and cheese
Pathogenic: Illness causing bacteria
Food Poisoning bacteria
• Usually need millions of bacteria to cause illness.
• The multiplication of bacteria within the food plays an important part in the disease
