ABSTRACT:
A deep walled pan is provided with the pan rim and upper wall portion forming a slightly cross sectional pan area greater than that of the pan cover. Between the pan rim and bottom, the wall is formed to provide a reduction in cross sectional pan area to less than that of the cover. The cover then can fit down into engagement with the pan wall to form with the pan bottom, an enclosed chamber utilizing only a small portion of the total pan volume. When corn kernels are placed on the pan bottom and the cover put in place, an energy saving low preheat is applied which quickly brings the small chamber up to popping temperature. Once the kernels begin to pop, a higher heat is applied. The expanding popcorn initially rises to the cover. Subsequently, the popping chamber automatically expands upwardly by virtue of the cover being forced upwardly within the pan by the expanding popcorn. During this expansion, the expanding chamber remains essentially closed, with the upper side wall portion of the pan functioning as a splatter shield during progressive raising of the cover and popped corn.
