30Helpful InformationMicrowave TermsArcing Arcing is the microwave term for sparks in the oven. Arcing iscaused by:• the metal shelf being installed incorrectly and touching themicrowave walls.• metal or foil touching the side of the oven.• foil that is not molded to food (upturned edges act likeantennas).• metal such as twist ties, poultry pins, gold-rimmed dishes.• recycled paper towels containing small metal pieces.Covering Covers hold in moisture, allow for more even heating and reducecooking time. Venting plastic wrap or covering with wax paperallows excess steam to escape.Shielding In a regular oven, you shield chicken breasts or baked foods toprevent over-browning. When microwaving, you use small stripsof foil to shield thin parts, such as the tips of wings and legs onpoultry, which would cook before larger parts.Standing Time When you cook with regular ovens, foods such as roasts or cakesare allowed to stand to finish cooking or to set.
