ABSTRACT:
Two plates (30&32) made of a solid, or very heavy sheet of heat resistant material with one side that is flat and one side that has grooves or other relief in the surface reducing the surface area on the otherwise uninterrupted plane of that side. This relief creates fins (38). One plate will have larger fins (38) with more surface area than the other plate. The plates (30&32) are attached to each other so that the flat or non-relieved sides of the plates face one another utilizing spacers (4) that keep the plates apart thus creating a primary air-gap (9) between the plates. Also supplied is a removable handle (40) which engages the plates in holes through each plate. The heat reducer is placed on a cooking heat source and a cooking vessel is placed on top of the heat reducer.
