GETTING TO KNOW YOUR MICROWAVE OVEN
The glass turntable of your microwave | Glass turntable |
oven lets microwaves pass through. Then |
|
they bounce off a metal floor, back through |
|
the glass turntable, and are absorbed by |
|
the food. |

Metal floor
Microwaves pass through most glass,
paper, and plastics without heating them
so food absorbs the energy. Microwaves
bounce off metal containers so food does not absorb the energy.
Microwaves may not reach the center of a
roast. The heat spreads to the center from the outer, cooked areas just as in regular oven cooking. This is one of the reasons for
letting some foods (for example, roasts
or baked potatoes) stand for a while after
cooking, or for stirring some foods during
the cooking time.
The microwaves disturb water molecules
in the food. As the molecules bounce around
bumping into each other, heat is made, like
rubbing your hands together. This is the heat that does the cooking.
NOTE: Do not deep fry in the oven.
Microwavable cookware is not suitable and
it is difficult to maintain appropriate deep frying temperatures.
