Carolina barbecue refers to a style of barbecue originating from the Carolinas in the southeastern United States. It is primarily known for its slow-cooked pork, which is often smoked over wood, giving it a distinct flavor. There are two main regional styles: Eastern North Carolina barbecue, which uses the whole hog and a vinegar-based sauce, and Western North Carolina barbecue, which typically focuses on pork shoulder and includes a tomato-based sauce. The sauces used in Carolina barbecue are key to its identity. The vinegar-based sauce in the east is tangy and thin, while the western style features a thicker, sweeter sauce. Carolina barbecue is often served with sides like coleslaw and baked beans, making it a popular choice for gatherings and celebrations.
