Comments
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.
• Freezer bags
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 special hints and tips).
