Sheilding
The thinner ends of joints of meat, or fish or the tips of poultry wings or legs can be shielded with small pieces of aluminium foil, to reflect microwaves away from these areas, to prevent them from cooking too quickly. The foil must never touch the walls of the oven.
Covering
Covering of food retains moisture and prevents splashing in a microwave oven. If you wish to develop a drier surface, do not cover or use only a paper towel. Wax paper, paper towels, plastic wrap, glass lids and cooking bags can be used for covering during microwaving. If a cooking bag is used. tie the bag loosely with string, leaving a small space for steam to escape. Place the bag in baking dish. For prolonged period of cooking, paper towels must not be used. If covering is not specified in a recipe, food can be left uncovered.
