Claims: I claim as my invention:

1. A food-warming serving base comprising:

a shaped upper wall having a radially outward periphery, and outwardly-upwardly inclined side portion just inwardly thereof, and a generally flat central recessed portion;

a lower wall sealingly joined to said upper wall about said periphery of said base and spaced vertically from said upper wall at said side and central portions thereof;

a layer of heat-insulating material placed between said upper and lower walls;

a solid, radially-continuous pellet of high heat-absorbency between said insulating material and said upper wall to contact said upper wall and release heat thereto; and

a thin, raised peripheral flange about said pellet adapted to contact an undersurface of said inclined side portion of said upper wall adjacent said central portion of said wall, said flange centering said pellet in said base upon said central portion.

2. The serving base of claim 1, wherein said central portion of said upper wall has a vertically raised center table surrounded by a relatively depressed ring and an inclined wall therebetween, and said pellet has a raised central portion uderlying and intimately contacting said raised center table and a radially-outwardly downward step to abut said inclined wall at a line along an undersurface thereof, the step and wall assisting said peripheral flange of the pellet in centering the pellet with respect to the base.

3. A serving base as defined in claim 1, wherein the lower surface of the pellet is substantially flat and has no contact with the lower wall of the base.
