Abstract
Microwave energy is utilized to energize an electroconductive film on a surface of a microwave browning apparatus to brown surface portions of foodstuff retained within said apparatus by conducting heat from said energized film through said browning apparatus to surface portions of the foodstuff. The microwave browning apparatus is provided with a recess below the electroconductive film, substantially surrounded by support portions, which function to focus or redirect the microwave energy toward central portions of the film or coating on the browning apparatus so as to provide more uniform browning temperatures across the coated surface.
