Abstract: To produce food-flavoring smoke and vapor in a gas or charcoal burner, a bed of wood flour is placed underneath the gridiron of the burner at a location which is out of the flames of the gas or burning charcoal. For example, a bed of wood flour may be placed upon a tray suspended from the gridiron. When placed at a location and in a manner to protect the wood flour and ignited, the wood flour will smolder, like burning punk, to emit smoke and vapor which is absorbed by food being cooked upon the gridiron.
