Abstract
Abstract A microwave heating susceptor for browning or searing packaged foods in a microwave oven. The susceptor is constructed from a thin metal mesh, and a microwave absorbing material applied to the metal mesh. To sear food, the suspceptor is placed in proximity to food in a microwave oven cavity. When the microwave oven is turned on, the susceptor heats to a high temperature, thereby browning and cooking the food.
