Tin foil is made of metal and cannot be directly heated under the action of "microwave". Any metal is easy to strike a fire under the action of microwave. Tin foil can be used under the action of "light wave" barbecue key, for example, roast chicken can wrap the wing tip and the first-class easy-to-cook part, and other parts can be left alone. Generally, the roasted chicken wings can be roasted with a metal grill under the combination of light waves, without tin foil, or in a heat-resistant glass container.
