For a richer, more complex flavor, consider adding a tablespoon of Worcestershire sauce or smoked paprika to the marinade. If you don't have a smoker box, you can create a foil pouch for the wood chips. Simply wrap the chips tightly in heavy-duty foil, poke a few holes in the top, and place it directly on the grill grate. Basting the chicken frequently during grilling helps to create a beautiful, caramelized crust. However, be careful not to baste too close to the end of cooking, as the sugars in the barbecue sauce can burn easily. Always use a meat thermometer to ensure the chicken is cooked to a safe internal temperature. Serve with your favorite BBQ sides such as coleslaw, potato salad, and corn on the cob for a complete summer meal.
