Abstract: A disposable flexible foil product placed on a barbecue grill comprises a sheet of metal foil with rectangular vents (15). The pattern consists of two sets of vents equally offset from the center with a space in the middle (17). The pattern is repeated longitudinally with a central divider (16) between patterns. The foil has a flat bottom surface. The foil is dispensable either from a roll or it is packaged in flat sheets or pans, having a scored line spaced in from the edge to allow for manual upturning of the edges.
