SUITABLE OVENWARE
To cook/defrost food in a microwave oven, the microwave energy must be able to pass
through the container to penetrate the food.
Therefore it is important to choose suitable cookware.
Round/oval dishes are preferable to square/oblong ones, as the food in the corners tends
to overcook. A variety of cookware can be used as listed below.
