South Carolina isn't the biggest state in the union, but it's deeply divided on its barbecue sauce. Some areas of South Carolina prefer a tomato-based sauce. Some prefer vinegar. And, in central South Carolina, the barbecue sauce of choice is mustard-based.
Many people trace the origins of the mustard sauce back to German settlers in the 18th century. The sauce usually contains yellow mustard, apple cider vinegar, brown sugar and various spices. You may also find recipes calling for honey or molasses.
Traditionally, the meat of choice for South Carolina barbecue is pork. Enthusiasts cook the pork over an open pit with hardwood coals. The sauce is added just before serving.
