A drip ring is supported in the base above the liquid reservoir. A cooking bowl is supported by the base and includes a bottom tray having an imperforate surface and a food support surface extending radially outwardly from the imperforate surface. The food support surface is defined by a plurality of alternating hill-like ridges and valley-like channels extending radially outwardly in concentrically spaced rings. The food support surface includes a plurality of vent holes for enabling steam generating in the reservoir to flow into the cooking bowl.
