Abstract
Abstract Disclosed herein is an apparatus for cooking which enjoys the duality of not only accommodating conventional cooking, but also provides a specific apparatus for the efficient cooking and preparation of various kinds of conventional and exotic pop corn recipes. When used in conventional cooking, the apparatus without the translucent lid according to the present invention corresponds to conventional cookware, but for the cooking of pop corn, the apparatus provides a translucent cover portion, insulating means between this cover and the lower pan portion, and an air gap disposed therebetween. The stirring attachment is suitably formed to not only stir the pop corn while it is being cooked, but also features a removable handle in which a forked extremity of a portion of the stirring attachment serves to provide a nesting area to remove the hot stirrer from the lid. A lid locking device serves to stabilize the lid's disposition on the lower pan element and ventilation is provided along the inner face between the handles and the area that supports the lid.
