Abstract
A cooking vessel includes a vessel body having a partially coated, textured stainless steel inner surface having a plurality of ribs rising above recesses having bottoms covered with a non-stick coating. The ribs have uncoated tops and sides that are separate from the bottoms of the cavities. The sides connect the tops to the bottoms. The tops rise above the non-stick coating covering the bottoms. According to the invention, the non-stick coating rises over the sides from the bottoms towards the tops without exceeding the height of the tops, and the bottoms and the sides have a rough surface under the non-stick coating. Also included is a method for producing a cooking vessel.
