Abstract

A cooking utensil that includes the combination of a heat transmitting metal bottom wall, preferably stainless steel with a heat generating source including a high heat-conductive metal body, preferably aluminum, the bottom wall having a substantially planar lower surface and said high heat-conductive metal body presenting a flat surface to the lower surface of the bottom wall, a plurality of releasable clamping devices carried by the bottom wall and projecting therebelow generally peripherally of the high heat-conductive metal body at spaced intervals therearound each clamping device including a threaded post and nut threadably engageable therewith and including a resilient washer for engaging and urging the metal body upwardly into full resilient abutment with the lower surface of the bottom wall and a releasable rigid support formation carried by the margins of the bottom wall to embrace and engage the metal body from below to bear upwardly thereagainst over the range of applied temperatures to thereby constrain the metal body against the bottom wall throughout the area of abutment to minimize distortion or warping of the bottom wall.
