Claim 3

The press of claim 1 wherein said bottom surface of said cooking plate has a mirror finish of about five microinches which is then anodized.

Claim 4

The press of claim 1 wherein said cooking plate is surrounded on its top and sides by a skirt, and said cooking plate is floating with respect to said skirt, said press having a handle thereon so that said cooking plate may be placed on the griddle or placed on a food product on the griddle.

Claim 5

The press of claim 3 wherein said handle is secured to said skirt and said cooking plate is movably mounted with respect to said skirt, said movable mounting of said cooking plate with respect to said skirt being such that when said cooking plate rests upon the griddle, and skirt rests upon the griddle around the periphery of said cooking plate.

Claim 6

The press of claim 3 wherein said cooking plate has an alloy contained therein which changes from liquid to solid when its temperature decreases through food product cooking temperature to give up heat to the food product.

Claim 7

The press of claim 5 wherein said alloy contained within said cooking plate changes phase from liquid to solid at about 350 degrees F.

Claim 8

The press of claim 1 wherein said cooking plate has an alloy contained therein which changes from liquid to solid when its temperature decreases through food product cooking temperature to give up heat to the food product.

Claim 9

The press of claim 7 wherein said alloy contained within said cooking plate changes phase from liquid to solid at about 350 degrees F.

Claim 10

A press for cooking a food product on a griddle, said press comprising: an aluminum cooking plate having a substantially flat substantially smooth lower cooking surface, said lower cooking surface being impregnated with a non-stick compound, the lower surface of said cooking plate being sufficiently large to reach the periphery of a cylindrical hamburger patty one half-inch thick weighing one-quarter pound, there being sufficient thermal mass in said cooking plate to cook a one-quarter pound frozen hamburger patty in two minutes when the griddle temperature is 375 degrees F. and said cooking plate is initially heated to between 350 and 375 degrees F.; said cooking plate having an alloy contained therein which changes from liquid to solid when its temperature decreases through food product cooking temperature of about 350 degrees F. to give up heat to the food product; a skirt having a top positioned over said cooking plate and having sides and ends extending downwardly around the periphery of said cooking plate, said cooking plate being floatingly mounted with respect to said skirt so that said cooking plate can move in a position wherein its lower surface lies in the same plane with said sides and edges of said skirt to a position where said cooking plate is entirely within said skirt; and a handle secured to said press so that said press may be placed on the griddle to be heated by the griddle and can be placed upon a food product on the griddle, said cooking plate having sufficient thermal mass that when it is heated substantially to griddle temperature when the griddle is at food product cooking temperature, and is thereafter placed on a food product on the griddle, said cooking plate supplies sufficient heat to the food product to cook substantially the upper half of the food product.

Claim 11

A press for cooking a food product on a griddle, said press comprising: an aluminum cooking plate having a substantially flat substantially smooth lower cooking surface, said lower cooking surface being impregnated with a non-stick compound, the lower surface of said cooking plate being sufficiently large to reach the periphery of a cylindrical hamburger patty one half-inch thick weighing one-quarter pound, there being sufficient thermal mass in said cooking plate to cook a one-quarter pound frozen hamburger patty in two minutes when the griddle temperature is 375 degrees F. and said cooking plate is initially heated to between 350 and 375 degrees F.; said cooking plate having an alloy contained therein which changes from liquid to solid when its temperature decreases through food product cooking temperature of about 350 degrees F. to give up heat to the food product; a skirt having a top positioned over said cooking plate and having sides and ends extending downwardly around the periphery of said cooking plate, said cooking plate being floatingly mounted with respect to said skirt so that said cooking plate can move in a position wherein its lower surface lies in the same plane with said sides and edges of said skirt to a position where said cooking plate is entirely within said skirt; and a handle secured to said press so that said press may be placed on the griddle to be heated by the griddle and can be placed upon a food product on the griddle, said cooking plate having sufficient thermal mass that when it is heated substantially to griddle temperature when the griddle is at food product cooking temperature, and is thereafter placed on a food product on the griddle, said cooking plate supplies sufficient heat to the food product to cook substantially the upper half of the food product.

Claim 12

The press of claim 9 wherein said cooking plate is floating with respect to said skirt by means of elongated studs secured to said cooking plate and passing through said skirt.

Claim 13

The press of claim 10 wherein said handle is secured to said studs.

Claim 14

The press of claim 11 wherein said non-stick compound impregnated into said anodized surface is a heat treated shortening compound such as is produced by heating the shortening coated anodized surface to 575 degrees F. for 20 to 30 minutes.

Claim 15

The press of claim 9 wherein said non-stick compound impregnated into said anodized surface is a heat treated shortening compound such as is produced by heating the shortening coated anodized surface to 575 degrees F. for 20 to 30 minutes.

Claim 16

A cooking plate having a non-stick surface comprising: a body having a substantially flat aluminum face having a smoothness of about 5 microinches; an anodized surface on said substantially smooth, substantially flat aluminum face, said anodized surface on said substantially smooth, substantially flat face having been reacted with shortening to produce a golden brown non-stick surface such as is produced when the shortening coated surface is heated at 575 degrees F. for a time of 20 to 30 minutes.

Claim 17

A cooking plate having a non-stick surface comprising: a body having a substantially flat aluminum face having a smoothness of about 5 microinches; an anodized surface on said substantially smooth, substantially flat aluminum face, said anodized surface on said substantially smooth, substantially flat face having been reacted with shortening to produce a golden brown non-stick surface such as is produced when the shortening coated surface is heated at 575 degrees F. for a time of 20 to 30 minutes.

Claim 18

The cooking plate of claim 14 wherein said cooking plate is incorporated into a hamburger press.

Claim 19

The cooking plate of claim 14 wherein said cooking plate has an alloy contained therein which changes phase from liquid to solid at about 350 degrees F. as its temperature decreases through this food product cooking temperature to give up heat to the food product.
