Question 7

Answer 7

Steaming is the Cooking of prepared foods by steam(Moist Heat) Under Varying degrees of pressure

Question 8

there are two main ways of steaming

Answer 8

In Low Pressure steaming food may be cooked by direct or indirect contact with the steam.
Direct, In a steamer or in a pan of boiling water,
Indirect, Between two plates over a pan of boiling water

High-pressure Steaming takes place in purpose-built equipment, which does not allow the steam to escape, therefore enabling steam pressure to build up, Increasing the temperature and reducing cooking times.

Question 9

advatages of steaming

Answer 9

Retention of nutritional value
makes some foods lighter and easier to digest
low pressure steaming reduces the risk of overcooking
High pressure steaming enables food to be cooked or reheated quickly because steam is forced through the food cooking it rapidly
Labour saving and suitable for large scale cookery
With steamed fish, the natural juices can be retained by serving with the fish or in making a sauce
Steaming is economical on fuel as a low heat is needed and a multi-tiered steamer can be used

Question 10

effects of steaming

Answer 10

When food is steamed its structure and texture is changed by a chemical reaction.

Food becomes edible once steamed.

Texture will vary according to the type of food being steamed, type of steamer used & the level of heat.
i.e. sponges/puddings are lighter in texture if steamed rather than baking

Question 11

health and safety

Answer 11

Boiling water is used in the bottom of steamers, so the same rules apply to steaming as to boiling.
Steam is extremely hot and can cause serious burns & scalds.

Poultry
Rice
Vegetables
Potatoes
 Sponge pudding

Question 13

definition of boiling

Answer 13

Cooking of Prepared foods in a liquid at Boiling Point

Liquids used
Water
Stock
Milk
Court-Bouillon

Question 14

why do we boil

Answer 14

A Healthier Method of Cookery
Does not use any fat
When done properly it does not lose nutritional value
Blanching foods - Then finished using another method
Helps break down the fibres in meat
Its economical - Using cheaper cuts
Can produce flavour with the stock made

Question 15

advantages of boiling

Answer 15

Pleasant to eating, Easy to digest
Tenderisation of meat
Appropriate for large scale cookery
Safe to eat – boiling can kill the bacteria present in some foods
labour saving, as requires little attention
Helps to retain colour in green vegetables
Control - Texture in blanching

Question 16

two ways of boiling

Answer 16

By adding food to boiling liquid:
Food starts to cook more quickly
It helps to retain the colour of green vegetables
Cooking Meat
Cooking Pasta and Rice
Easier to control texture (al dente / crisp)

By starting food off in a cold liquid:
Bringing food to the boil slowly may help to extract flavours from the food
It is less likely to damage shape and structure of the food as water is not moving rapidly from the start
Root vegetables and Pulses
Stocks and Soups
Impurities (scum) will come off some foods whilst being heated, this can then be skimmed off the top

Question 17

health and safety

Answer 17

It is important to think about health and safety when you are working with boiling liquids.
Make sure that pan handles are turned in.
Always lower food into boiling liquids, this will prevent splashing and scalding.
When removing a lid, tilt it away from you, to allow the steam to escape safely.
