Abstract

A method of producing an edible food product includes the step of forming a vessel core with a first material having a first level of susceptibility to heating by induction. The method also includes the step of casting an apron of a second material with a second level of susceptibility to heating by induction lower than said first level around at least a first portion the vessel core in an in situ casting process to form a clad cooking vessel having a cooking surface. An uncooked food product is then disposed on the cooking surface of the clad cooking vessel and heated to produce the edible food product by subjecting the vessel core to a magnetic field.

Claims (13)

1. A clad cooking vessel for cooking food product using induction heating comprising:

at least one vessel core formed of a first metal material having a first level of susceptibility to heating by induction; and

an apron disposed in integral and surrounding relationship with said at least one vessel core to define a cooking surface;

said apron formed of a second metal material with a second level of susceptibility to heating by induction lower than said first level of susceptibility of said at least one vessel core; and

said at least one vessel core including a plate portion and a plurality of posts extending from said plate portion and said cooking surface of said apron including a plurality of lands and grooves surrounding said plurality of posts to reduce the likelihood of variation in surface temperature of said cooking surface during induction heating.

2. The clad cooking vessel as set forth in claim 1 wherein said apron defines a cooking surface with a plurality of lands and grooves.

3. The clad cooking vessel as set forth in claim 1 wherein said apron defines a plurality of discrete cooking surfaces.

4. The clad cooking vessel as set forth in claim 3 wherein said apron includes a wall surrounding at least one of the discrete cooking surfaces.

5. The clad cooking vessel as set forth in claim 4 wherein said apron includes a plurality of walls, each wall surrounding at least one of said discrete cooking surfaces and separating said cooking surfaces from one another.

6. The clad cooking vessel as set forth in claim 3 wherein said at least one vessel core is disposed below all of said plurality of discrete cooking surfaces.

7. The clad cooking vessel as set forth in claim 3 wherein said at least one vessel core further comprises a plurality of cores, one core being disposed below each of said plurality of discrete cooking surfaces.

8. The clad cooking vessel as set forth in claim 1 wherein said first metal material comprises iron.

9. The clad cooking vessel as set forth in claim 1 wherein said second metal material comprises aluminum.
