Water, sugar and fat in food absorb microwaves and
causes their molecules to vibrate. This creates heat by
friction, in the same way your hands get warm when
you rub them together.  
The outer areas of  food are heated by microwave
energy and the remaining portions by conduction.  It is
important to turn, rearrange or stir food to ensure
even heating.  Where recommended, allow food to
stand, this is not optional but is necessary to ensure
thorough cooking. It is particularly important for dense
food, such as joints of meat.

• Microwaves pass through non-metallic dishes and

utensils and heat the food inside the dishes. 

• Microwaves are reflected by metal. 
• The oven is lined with metal and has a fine metallic

mesh in the door to prevent microwave leakage.

• Metallic dishes are not suitable for microwaving. 
• See SUITABLE COOKWARE, page 22-23.
