Barbecue chicken is a popular dish made by cooking chicken pieces over an open flame or grill, often coated with a flavorful sauce. The chicken can be marinated beforehand to enhance its taste, and common cuts include wings, thighs, and breasts. The sauce used in barbecue chicken typically contains ingredients like tomato, vinegar, sugar, and various spices, giving it a sweet and tangy flavor. Cooking methods can vary, with some people using a smoker for a deeper flavor, while others prefer grilling for a charred finish.
