The improved culinary sheet is useful in the production of a culinary pan liner, such as a pie pan liner or the like. The sheet and liner are characterized by having a matrix of either a body of cellulosic fibers or a thermoplastic film, or both, in which are substantially uniformly distributed a plurality of discrete metal foil particles. The foil can be one or more of aluminum foil, tin foil, titanium foil, bronze foil, brass foil or copper foil. The concentration of foil particles in the matrix varies to control the strength, thermal properties and other characteristics of the sheet and liner. Preferably, the sheet and liner define a plurality of openings extending from the upper surface to the lower surface of the sheet and liner and disposed along the length and width of the sheet and liner. The openings control thermal and moisture transfer through the sheet and liner. The liner and sheet can be multi-ply with plies being bonded together with layers of wax or the like. The sheet and lienr can have the metal foil particles in both the thermoplastic film and body of cellulosic fibers, such as paper, where both are present.
