A method and apparatus for cooking a wide variety of foods wherein the food to be cooked is placed in contact with a sheet of conductive material, which has been connected by clamping members to an electrical power source capable of supplying a low voltage, high current. A food may be wrapped in a thin sheet of conductive material, such as a metal foil, and cooked by passing current through the thin sheet or foil. The process is characterized by a high efficiency and short cooking time. Preferred conductive material are disposable, for example aluminum foil, thereby avoiding cleaning after cooking.
The apparatus includes means for supplying a high current, at a low voltage. Electrically connected to the current supply means are a pair of clamps for clamping an electrically conductive sheet. Preferably, the clamps are independently operable and each comprise a curved movable member and a fixed member, together with means for moving the movable member.
