Abstract
A combination bake oven/steamer/broiler cartridge for cooking food on a cooktop. A heat source is placed on a pan within a cooktop frame. A cartridge is placed over the heat source and inserted into the pan. The heating device warms the cartridge. The cartridge can be selectively configured as a bake oven, steamer or broiler. To configure a bake oven, an adjustable rack is placed in the cartridge to hold the food. A cover is then placed over the cartridge to contain heat. To configure a steamer, water is added to the bottom of the cartridge. A steaming pan is then placed in the cartridge. The cartridge is then covered. The water is then heated to make steam. By substituting a ceramic or glass container for the steaming pan, the steamer functions as a warming device. To configure a broiler, a special cover containing heating elements is placed over the adjustable rack.
