For an even deeper smoke flavor, consider brining the chicken thighs for at least 4 hours, or up to overnight, before seasoning and smoking. Experiment with different types of wood chips, such as hickory or applewood, to customize the smoke profile to your preference. Each wood imparts a unique flavor. If you don't have a smoker, you can achieve a similar result using a grill with a smoker box or by wrapping wood chips in foil and placing them directly on the coals.
