Cookware for searing
An article of cookware has an interior cooking surface that with raised linear or curvilinear bands with an outer layer of a first material that is one of ceramic or metallic in nature to provide cut and abrasion resistance. Valleys or grooves between the raised bands have an outer layer of a second material with low surface energy to facilitate food release and cleaning of debris. The bands are arranged to protect the second material from cutting and abrasion that would damage the second material. The bands aid in enhancing distribution of cooking oil to enhance searing and browning of foods.
1. An article of cookware, comprising:
a surface for supporting foodstuffs during cooking, the surface comprising
a first region defined by a plurality of planar bands of a first material, the planar bands spaced apart from each other by at least a first distance, and
a second region defined by a plurality of intervening channels between the planar bands, the intervening channels having surfaces disposed below an upper surface of immediately adjacent planar bands and an outer surface of a second material with a lower surface energy than an outer surface of the first region.
2. The article of cookware according to claim 1 , wherein the first material is one of a metal, a metal alloy, a metal compound, or a ceramic compound.
3. The article of cookware according to claim 2 , wherein the second material is a non-stick coating that comprises one of fluoro-polymers, silicones, or fluoro-silicones.
4. The article of cookware according to claim 1 , wherein the second material is a non-stick coating comprising one of fluoro-polymers, silicones, or fluoro-silicones.
5. The article of cookware according to claim 1 , wherein the surface of the intervening channels have curvilinear shape transverse to a principal axis of the planar bands of the first region.
6. The article of cookware according to claim 1 , further comprising a third region defined by a plurality of intervening surfaces between each of the first regions and second regions which comprises intervening planar bands disposed at about a same height as the planar bands of the first region in which the outer surface of the intervening planar bands comprises the second material.
7. The article of cookware according to claim 6 , wherein the intervening planar bands are narrower than the planar bands of the first region.
8. The article of cookware according to claim 1 , wherein the planar bands of the first region have a width of at least about 2.5 to 4.5 mm.
9. The article of cookware according to claim 1 , wherein the intervening channels have a width of at least about 0.5 to 2 mm.
10. The article of cookware according to claim 1 , wherein the planar bands have an elongated curvilinear shape.
11. The article of cookware according to claim 1 , further comprising an upward extending sidewall that surrounds the surface for supporting foodstuffs.
12. The article of cookware according to claim 1 , wherein the planar bands have an elongated curvilinear shape and are circular, each planar band forming a concentrically aligned annular ring with respect to the other planar bands in the plurality of planar bands.
13. The article of cookware according to claim 1 , wherein the article of cookware has a base material and the surface for supporting foods stuffs is above the base material.
14. The article of cookware according to claim 13 , wherein the base material is selected from the group consisting of aluminum, stainless steel, cast iron and ceramic materials.
15. The article of cookware according to claim 1 , wherein the intervening surfaces are disposed slightly lower than an upper surface of the immediately adjacent bands and have a convex shape.
