Barbecue sauces are flavorful condiments used to enhance grilled or smoked meats. They typically combine ingredients like tomatoes, vinegar, sugar, and various spices, resulting in a sweet, tangy, or smoky taste. Different regions have their own unique styles, such as Kansas City sauce, known for its thick, sweet profile, and Carolina sauce, which is often vinegar-based and tangy. These sauces can be used as marinades, basting agents during cooking, or as dipping sauces. They add moisture and flavor to dishes like ribs, pulled pork, and chicken, making them a popular choice for outdoor cooking and gatherings.
