In any discussion of barbecue, North Carolina likes to describe itself as the "Capital of 'Cue". And when you're talking barbecue in North Carolina, you are talking about one thing and one thing only: pork. Forget the brisket, the chicken, even ribs for that matter, it's all about the hog here in NC.

In the east, purists focus on cooking the whole hog, whereas western North Carolina 'cue, often called "Lexington Style" is just the shoulder. Eastern barbecue joints also give you a liquidy pepper-vinegar sauce whereas in the west you are more likely to find what most would consider a more traditional barbecue sauce, but still heavy on the vinegar...
