A cooking apparatus comprises a trough, a well, and a pot. The trough is configured to hold a first cooking medium. The trough has insulated floors, insulated walls, and a steam pipe as a heating element to directly heat the first cooking medium. The well is joined to a cover plate. The cover plate is configured to fit over the trough with a seal, such that at least a portion of the well extends into the trough for submersion into the first cooking medium. The pot is inserted in the well. A second cooking medium may be introduced in the well adjacent to the pot. A food product such as goetta may be introduced to the pot for cooking. Heat may be transferred from the heating element, to the first cooking medium, to the well, to the second cooking medium, to the pot, and then to the goetta.
