Abstract

A cooking device for cooking items over a heat source has a base with an annular reservoir having an inside rim defining an opening, a substantially circular cooking plate supported by the base, a rack supported by the base over the cooking plate, and a lid supported by the base over the cooking plate and the rack. The base of the cooking device has an annular cooking plate supporting surface located radially outwardly from an outside rim of the annular reservoir, an annular rack supporting surface located radially outwardly from the cooking plate supporting surface, an annular lid supporting surface located radially outwardly from the rack supporting surface, an outer rim projecting radially outwardly and upwardly from the lid supporting surface, an upwardly-projecting annular sealing portion located intermediate the rack supporting portion and the lid supporting portion, an annular cooking plate retaining surface disposed radially outwardly from the cooking plate supporting surface, and discrete support elements projecting downwardly from the base. A reversible cooking plate has a grilling surface on one side and a griddle surface on an opposite side. In one position, the grilling surface is directed upwardly and is inclined at an angle, in a second position, the griddle surface is directed upwardly and is substantially horizontal. A rim of varying height extends around the periphery of the griddle surface and aligns the griddle surface at an angle when in the first position.
