Abstract
A food preparation device may include at least two energy sources, a chamber into which at least two types of energy are providable via the at least two energy sources, and a cooking controller operably coupled to the at least two energy sources to selectively distribute power to respective ones of the at least two energy sources. The at least two energy sources may include a radio frequency (RF) capacitive heating source and a cold air source.
