While it is not recommended to use charcoal directly in a gas grill, there are methods to incorporate charcoal flavor when using a gas grill. Here are a couple of techniques you can try:
Charcoal Briquettes in a Smoker Box: Many gas grills have a smoker box or a dedicated area where you can place wood chips or charcoal briquettes. These boxes are designed to allow the charcoal to smolder and produce smoke while not directly coming into contact with the gas burners. By placing a few charcoal briquettes in the smoker box, you can infuse your food with a subtle charcoal flavor. Soak the briquettes in water for about 30 minutes before placing them in the box to help them smolder slowly.
Charcoal Chimney Starter: Another method is to use a charcoal chimney starter alongside your gas grill. Fill the chimney starter with charcoal and light it using a newspaper or fire starter cubes. Once the charcoal has ashed over and is glowing red, carefully transfer the lit charcoal to one side of your gas grill. Place your food on the opposite side, ensuring it is not directly over the lit charcoal. The lit charcoal will provide indirect heat and a smoky flavor to your food, while the gas burners can be used to regulate the temperature.
It's important to note that when using these methods, you should follow the safety guidelines for your specific grill and never place charcoal directly on the gas burners. Always consult your grill's manual for instructions on using wood chips, smoker boxes, or charcoal with your gas grill.
