Abstract: A heat storage dish for use with food serving ware such as a plate or the like has upper and lower dish walls of generally complementary peripheral configuration, with the walls being secured together at their peripheries and the remainder of the walls being spaced from each other to define a cavity therebetween. A heat storage plate is positioned in the cavity between the walls, and the plate has at least one opening formed therein. The plate is held in close heat transfer relation to the upper wall by a flange support member which is secured to the upper wall and extends through the openings to a pair of outwardly extending flanges on which the plate is supported. A layer of heat insulating material extends entirely across the bottom of the plate, between the bottom of the plate and the bottom wall, to prevent heat losses from the plate through the bottom wall of the dish.
