Abstract
A baking device, such as a cookie sheet, includes a textured pattern on an upper surface of an upper metal sheet. The textured pattern includes a plurality of protrusions separated by recessed portions. The protrusions each have an upper food contacting surface which minimizes contact with a food product baking on the upper sheet so that the food product may be easily removed. The baking device may also include a polymeric coating to further enhance the non-stick properties of the baking device.
Claims20
A baking device for baking a food product, comprising:
- a first metal layer including an upper surface to support the food product when placed thereon, the upper surface having a textured pattern comprising a plurality of evenly spaced, substantially straight rows of protrusions, each protrusion having an upper food contacting surface and a side surface;
- and
- a second metal layer connected to the first metal layer such that an air pocket is formed therebetween,
- wherein adjacent rows of the protrusions are separated by a substantially flat recessed portion extending continuously between the side surfaces of adjacent protrusions, and the upper food contacting surface of each protrusion has a height relative to the substantially flat recessed portion in a range between 0.002 and 0.050 inch.
A baking device, comprising:
- a first metal layer;
- and
- a second metal layer connected to the first metal layer such that an air pocket is formed therebetween, the second metal layer having an upper surface having a patterned surface area,
- the patterned surface area including a textured pattern having a plurality of evenly spaced, substantially straight rows of protrusions separated by substantially flat recessed portions lying in a first plane and extending continuously between adjacent rows, each protrusion having an upper food contacting surface lying within a second plane parallel to and disposed above the first plane, the second plane having an area,
- wherein the upper food contacting surfaces have a contact area that is less than or equal to one-third the area of the second plane.
A baking device for baking a food product, comprising:
- a first metal layer having an upper surface;
- and
- a second metal layer connected to the first metal layer such that an air pocket is formed therebetween;
- wherein the upper surface of the first metal layer includes a textured pattern comprising a substantially flat portion disposed in a first plane and a plurality of rounded protrusions, each protrusion having an upper food contacting surface that lies in a second plane disposed above and substantially parallel to the first plane and a side surface extending between the first and second planes, the substantially flat portion extending continuously between the side surfaces of adjacent protrusions.
