If you don't have a smoker box, there are still two easy methods to use wood chips for smoking: - Foil Packet Method: Take a sheet of aluminum foil and place a handful of wood chips in the center. Fold the foil tightly to create a sealed packet, leaving a small vent on top for smoke to escape. Place the foil packet directly on the hot coals or on the grill grates over the heat source. As the packet heats up, the wood chips will begin to produce smoke. - Pellet Tube Method: A pellet tube is a small cylindrical container filled with wood pellets. Simply fill the tube with your desired wood pellets and light one end. Let it burn for a few minutes until it starts producing smoke. Place the lit pellet tube on the grill grates or directly on the charcoal. The tube will continue to smolder, releasing smoke throughout the cooking process.
