SUITABLE COOKWARE
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.
