Abstract
A food item is wrapped with plastic film or other dielectric substrate having a very thin coating thereon which controls the microwave conductivity when the package is placed within a conventional microwave oven. The plastic film or other substrate and its coating conform to a substantial surface portion of the food item. The coated plastic film or other substrate converts some of the microwave energy into heat which is transmitted directly to the surface portion so that a browning and/or crispening is achieved. The coating has the additional capability of modifying the microwave field configuration so as to further enhance the heating of the food surface immediately adjacent the film in which the food is packaged. The microwave energy not converted into heat by the coated film passes through the film to dielectrically heat the single food item as is normally done when cooking with microwaves.
