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.
