Certain frozen foods, as deep fat fried foods and baked and leavened products, are, during a microwave exposure, buffered against microwave edge and spot heating by enclosing said food within a microwave-permeable, vapor-resistant, heat-resistant enclosure which can employ a vapor release means. Where, within said enclosure and around said food, a microwave-permeable, transparent-to-liquid-and-oil-under-pressure, plastic film is enclosed in a water-and-oil-absorptive, microwave-permeable material and where the defrosting, heating and subsequent cooling can be temperature monitored, where the results can be varied by using water and salt water and where baked and leavened products useful life can be extended by the timely application of water.

For use in a microwave oven, a food package which comprises: a microwave-permeable, non-liquid-absorptive inner member for covering a food, a plurality of openings, through said inner member, of sufficient size to permit liquid, food by-products to transfer across said inner member when said liquid, food by-products are in motion due to exposure of said food to microwave radiation and of sufficient size to prevent said transfer of said liquid, food by-products when said liquid, food by-products are not in motion due to exposure of said liquid, food by-products to microwave radiation, a microwave-pemeable, liquid-absorptive material in contact with, at least, a part of said inner member\s outside surface, and an outer microwave-permeable, liquid-non-permeable, non-microwave-absorptive enclosure which forms a heating chamber and encloses said inner member and said liquid-absorptive material. A method of defrosting and heating, in a microwave oven, a frozen food, the steps which include: enclosing said food in an inner, microwave-permeable plastic film which film contains a plurality of openings of sufficient size to permit the passage across said film of liquid-and-oil by-products of said food when under pressure due to exposing said food to microwave-radiation and of sufficient size to limit the passage across said film of said liquid-and-oil when said liquid-and-oil is not under said pressure due to said exposure to microwave radiation, completely enclosing said food and said inner film in an outer microwave-permeable container fabricated to contain vapor, water and oil therein, placing a water-and-oil-absorptive material between said inner film and said outer container, and exposing said food to microwave radiation until said food defrosts and heats.
