Abstract: A single-unit, ready-to-use device for flavoring food by smoking on a barbecue grill using gas or other fuels. This invention is a small, convenient cartridge containing small pieces of one of the aromatic woods, such as Hickory or Mesquite, etc., or any combination thereof. The package can contain draft vent perforations to allow enough air to flow in to promote charring without allowing ignition, and smoke to flow directably out. In use, the package is placed directly on the gas-heated lava rocks, burning charcoal, or other fuel. The wood chips within the package quickly begin to char and emit smoke, thus flavoring the food placed within the gas grill enclosure. When the process is complete, the cooled package can be easily disposed of along with the other household refuse, or it can be saved for recycling. Multiple cartridges can be made available in multi-cartridge carriers and more than one cartridge can be used simultaneously or sequentially.
