This whole smoked chicken gets its bold flavor from a homemade Cajun spice rub. A mix of black, white, and cayenne peppers brings serious heat, while cumin and nutmeg add warm, earthy notes. Smoking the bird slowly over hickory wood chips keeps the meat tender and infuses it with a deep, savory aroma. It is an excellent centerpiece for a weekend barbecue or a relaxed outdoor dinner. Serve it alongside grilled vegetables and crusty bread to complete the meal.
