Abstract
Disclosed is a new "universal" heat distribution article for replacing a rack supporting lava rock or a custom-fitted heat distribution plate. The article includes at least a pair of plates (and preferably four plates), each of which has rows of apertures. The plates are in partial overlapping contact with one another and those apertures at the kettle central region are at least partially closed by the other plate. On the other hand, those plate apertures at the kettle side perimeter regions are fully open. Upward air flow at the kettle central region is restricted, heat is distributed toward the sides of the kettle and the temperature gradient across the cooking surface is materially improved. A retrofit kit and details of the heat distribution plate are also disclosed.
