For food to cook in the microwave oven,
the microwaves must be able to penetrate
the food without being reflected or
absorbed by the dish.
It is important to choose the correct
cookware, therefore, look for cookware
that is marked microwave-safe.
The following table lists various types of
cookware and indicates if and how they
should be used in a microwave oven.
MICROWAVE-SAFE UTENSILS
If you are not sure whether an item is microwave-
safe, you can perform the following simple test:
1. Place 1 cup of water (in a glass-measuring cup)
inside your oven next to the item to be tested.
2. Press the Add 30 sec button twice to heat them
both for one minute at high power.
After one minute, the water should be warm and
the item you are testing should be cool. If the dish
is warm, then it is absorbing microwave energy
and is not microwave-safe.
