North Carolina barbecue often starts with a spice rub. From there, are two different styles of barbecue in North Carolina - East and West. The Eastern style uses a vinegar/spice sauce. The Western style uses a sauce that's still vinegar-y but also has a bit of tomato or ketchup in it. This pulled pork is more of the Western style because there is a bit of tomato in the sauce, and the pulled pork is made with pork butt or pork shoulder.
