ABSTRACT:
A lightweight cooking utensil with raised side walls and a high temperature flexible plastic sheet stretched across the bottom portion of the side walls and sealed thereto to form a leak-proof container. The utensil is adapted to be heated on a low energy, low temperature solid plate surface heating unit with a slight convex top surface so that the plastic sheet of the utensil will conform to the top surface and make a highly efficient thermal coupling.
