Abstract
Abstract A cooking utensil including pan, base, and cover elements, each formed with annular outwardly extending flanges or lips about its periphery for cooperative stacking engagement to provide a portable oven or the like. The utensil is particularly useful for the baking of pizza or the like on a stove top, an electric hot plate, or over a camp fire. The base and pan elements have a specially configured construction including a plurality of openings in the sides thereof such that when stacked together, they cooperatively provide a heat-deflection chamber to direct the heat from a source below the base into an oven chamber formed between the pan element and its matching cover. The pan element also includes an annular trough or ridge to hold additional batter which, when heated, rises to form a thickened edge crust about the pizza.
