Can be used to warm foods or
liquids. Delicate glass may break or
crack if heated suddenly.
• Glass jars
✓
Must remove the lid. Suitable for
warming only.
Metal
• Dishes
✗
May cause arcing or fire.
• Freezer bag twist ties
✗
Paper
• Plates, cups,
napkins and kitchen
paper
✓
For short cooking times and
warming. Also to absorb excess
moisture.
• Recycled paper
✗
May cause arcing.
Plastic
• Containers

Particularly if heat-resistant
thermoplastic. Some other plastics
may warp or discolour at high
temperatures. Do not use Melamine
plastic.
• Cling film
✓
Can be used to retain moisture.
Should not touch the food. Take
care when removing the film as hot
steam will escape.

Only if boilable or oven-proof.
Should not be airtight. Prick with a
fork, if necessary.
Wax or grease-proof
paper
✓
Can be used to retain moisture and
prevent spattering.

MICROWAVES
Microwave energy actually penetrates food, attracted and absorbed by its water,
fat and sugar content.
The microwaves cause the molecules in the food to move rapidly. The rapid
movement of these molecules creates friction and the resulting heat cooks the
food.
COOKING
Cookware for microwave cooking:
Cookware must allow microwave energy to pass through it for maximum
efficiency. Microwaves are reflected by metal, such as stainless steel, aluminium
and copper, but they can penetrate through ceramic, glass, porcelain and plastic
as well as paper and wood. So food must never be cooked in metal containers.
Food suitable for microwave cooking:
Many kinds of food are suitable for microwave cooking, including fresh or frozen
vegetables, fruit, pasta, rice, grains, beans, fish, and meat. Sauces, custard,
soups, steamed puddings, preserves, and chutneys can also be cooked in a
microwave oven. Generally speaking, microwave cooking is ideal for any food
that would normally be prepared on a hob. Melting butter or chocolate, for
example (see the chapter with tips, techniques and hints).
Covering during cooking
To cover the food during cooking is very important, as the evaporated water rises
as steam and contributes to cooking process. Food can be covered in different
ways: e.g. with a ceramic plate, plastic cover or microwave suitable cling film.
Standing times
After cooking is over food the standing time is important to allow the temperature
to even out within the food.
