Abstract
A device for heating and warming food featuring a base with a central member axially projecting it surface which provides heat from its exterior surface. The base is cooperatively engageable with one or a plurality of cooking containers having central cavities adapted to frictionally engage the central member thereby heating food in the containers from a central axis. Secondary cooking containers are engageable to axial projections in the primary cooking contains to allow two foods to be heated at the same time from a central area.
Claims21
A cooking apparatus for food comprising:
- a base, said base having a top surface;
- a central member axially projecting from an engagement end on said top surface, to a distal end;
- said central member having an exterior dimension defined by a sidewall engaging an upper surface at said distal end;
- means for radiating heat positioned on said exterior of said central member;
- at least one cooking container, said cooking container having a cooking cavity defined by a sidewall extending from a bottom wall to an open end opposite said bottom wall;
- a central cavity, said central cavity having an internal dimension defined by a center wall engaging said bottom wall about the circumference of an aperture communicating through said bottom wall, said internal cavity extending to a top wall at a distal end of said center wall;
- said center wall extending to said top wall also defining an internal member axially projecting into said cooking cavity from said bottom wall to a distal end of said internal member;
- and
- said internal dimension of said central cavity adapted for cooperative removable engagement with said exterior dimension of said central member, whereby said cooking container is removably engageable upon said base with said central member operatively engaged in said central cavity and food placed in said cooking cavity is heated by heat radiated from said central member occupying said central cavity.
