Abstract
Abstract A grooved baking pan and a method for baking therewith wherein the bottom surface of the pan is provided with a plurality of grooves. In the preferred embodiment, the grooves are V-shaped. The grooves are arranged in a pattern such as a grid pattern and apertures are located in the areas bounded by the intersecting grooves. The pan is used to bake high density food products such as pizza in an impingement oven wherein columns of heated air are formed which are directed at localized areas of the bottom surface of the pan. The pan is moved relative to the impinging air columns while the food product is being baked.
