ABSTRACT:
Pizza pan shielding systems and methods generally include one or more of the following: a pan, a bottom shield, a top shield, and a ring shield. Each of these elements preferably incorporates a plurality of perforations. The size, location and density of these perforations, and/or the material make-up of the element(s), determine whether certain types of baking energy from various heat sources will reach a food item located within the system. Substantial evenness of cooking results, in a short time period and at reasonably baking temperatures. Embodiments of the invention address the problems of underbaking in central areas of the food item and overbaking, dryness, microwave-induced toughness or burning of outer areas of the food item, such as a crust area. Embodiments of the invention have particular, though not exclusive, application to the pizza-baking devices and methods.
