Barbecue sauce is a flavorful condiment commonly used in grilling and cooking meats. It typically combines ingredients like tomatoes, vinegar, sugar, and various spices to create a sweet, tangy, and sometimes smoky flavor. Different regions have their own unique styles, such as Kansas City sauce, which is thick and sweet, and Carolina sauce, known for its vinegar base. This sauce can be used as a marinade, a basting sauce during cooking, or a dipping sauce served alongside grilled foods. It enhances the taste of meats like ribs, chicken, and pulled pork, making them more enjoyable and flavorful.
