Settle down, settle down. I don't think you know what barbecue sauce in North Carolina means. What it amounts to is vinegar and a a variety of chile powders. There is no tomato or sugar involved; it is a watery, spicy delicious seasoning.
I just finished a sandwich, with cole slaw on top. I had a lot of these sandwiches when I lived in North Carolina and this one would stand up against the best of them.
Oh, I thought you meant the thick bbq sauce. Anyway, watch the video on that page above I posted. They do things with pork shoulder that are beyond belief.
