Abstract
A double-walled cooking utensil provides inner and outer metal layers which are nested together and permanently connected along peripheral flanges. Each layer provides a planar bottom portion which cooperate with each other to define a thin chamber therebetween. A sheet of reflective aluminum is positioned in such chamber and resists the transfer of radiant heat from the bottom surface of the outer layer to the bottom surface of the inner layer which constitutes the cooking surface of the utensil. The reflective sheet is embossed with a grid of ribs which extend toward the outer layer and maintain a small spacing between the portions of the reflective layer between the ribs. The utensil promotes quality baking without requiring increased baking time, and produces bakery having more uniform texture and better color.
