1. In a pressure cooker having an upwardly opening cooker body to which there is removably affixed a lid, with seal means between the lid and body to provide a sealed enclosure, and a pressure regulator means by which the pressure within the sealed enclosure is regulated to a value above ambient, the improvement comprising:

  • an upwardly opening food container of a size to be received within said body, such that an annulus is formed between the body and the container;

    means supporting the container bottom in spaced relationship respective to the bottom of the body to form a boiler therebetween;

    a cover plate removably received at the upper end of said container for closing the opening in said container;

    said cover plate, said container, and said lid jointly form a vapor space above said cover plate;

    said cover plate is a relatively thick heating plate which forms a heat sink so that the plate can be preheated to a temperature above 400°

    F. and subsequently placed into position whereupon the upper surface area of any food contained within the food container is heated;

    said cover plate is provided with a plurality of apertures;

    an elongated heat conducting rod received through each of said apertures, such that one marginal end of said rod is disposed within said vapor space and the other marginal end thereof is disposed within said container;

    whereby water can be placed within the boiler, the bottom of the cooker body elevated in temperature to cause the boiler to form steam, whereupon the steam flows up through the annulus, into the vapor space, and is exhausted through the pressure regulator to ambient without condensing onto the heated cover plate.
