Abstract: A disposable cover for covering the cooking surface of an outdoor charcoal fueled barbecue grill and directing the quantity and flow of air beneath the cover when it is placed onto the cooking surface of said grill. The cover is made from a manually formable material having a plurality of perforations arranged in rows, the perforations of each of the rows being in staggered radial relationship with the perforations of adjacent rows. The outward facing side of the cover has a highly polished shiny reflective metallic finish for reducing the radiant heat transfer from the grill and the inwardly facing surface has a coating of aromatic wood chips and a bonding agent for enhancing the flavor of food cooked on the grill.
