The purpose of the present invention is to use commercial aluminum foil to reduce stains on a grill net, a tray, or the like, and to make repeated heat cooking possible without cleaning, merely by replacing the foil. In the present invention, a roller (15) is used to form grooves (10) and cylinders (9) inclined relative to an axis, and the roller (15) is used to perform a rolling motion over a net, whereby constant and uniform concavities are created and undulations are formed on the net. Concavities are thereby created between the rods (12) of a grill net; stain-causing excess oil, moisture, and the like from foodstuffs can be accommodated; stains and washing can be reduced; and the grill net can be repeatedly used merely by replacing the aluminum foil with each use after cooking, without washing. |
