All NC-BBQ is very slow cooked pork carcasses, generally cooked for a minimum of 16-18 hours at a very low temperature for pork, often 250 degrees or slightly less, sometimes up to 300 degrees but never more than that. With the (very real) safety concerns about parasites in pork, it's important for the pork to be cooked completely through, obviously; if you ever see any pink meat in NC-BBQ, quit eating it right then, and raise hell. After cooking, the meat is pulled from the bones, and then pulled apart into bite-size chunks, and then usually chopped further with a large cleaving knife until a texture is reached that suits the chef. Almost never is "real" NC-BBQ ever served sliced, except at certain restaurants that cater a lot to non-NC-natives and the clientele demands such.
By slow cooking at low temperature, the meat is allowed to "age" without drying out. Almost never is any kind of sauce applied during cooking, save a tad of vinegar-based with a few spices only "sauce" which isn't meant as a flavoring agent, only as a hydration aid to prevent excess binding of the outside part of the meat. I've never cooked a hog in my life, NC-style or any other way, not for a pig-picking (more on the cultural grail of NC-style "pig-picking's" later) or any other reason, so I'm not going to claim to know let alone understand the culinary alchemy that takes place by staying up all night and maintaining the vigil of monitoring the carcass until the next day. All I know is that cooking NC-style pork BBQ is a great job for insomniac carnivores with enhanced tastebuds.
Eastern-NC-Style
It's easier to be a Master Chef at the New York Academy Of Culinary Arts & Sciences, it's easier to be be a Professor Of Sanskrit at the Sorbone, it's easier to be a Master Steak Chef at Blackie's in DC, than it is to be a Master BBQ Chef Of Eastern-NC-BBQ. That's because Eastern-NC-Style BBQ is plain whole-hog pork meat, with just the tiniest bit of vinegar-based "sauce" which isn't a sauce at all, applied as a moistening agent. Eastern-Style BBQ is usually one of two grades; either excellent, or close to inedible. When you have a fine-chopped (almost to the point of being ground at times, without use of a mechanical grinder) plain meat dish, with just enough vinegar "sauce" to wake up your tastebuds and nothing else, the meat, the grade of the meat, how the pig is butchered and prepared, the pain-staking slow-cooking process, everything culminates to when it hit's your tongue with either an "ahhhhh" or a "yecchhh!".
"The Eastern-NC-Style Sauce"
1 cup plain vinegar
1 teaspoon crushed red pepper
1 teaspoon salt
1/4 teaspoon black pepper
3 drops of lemon juice
Using an icepick, poke holes through the meat as deep as possible, using a rough 1"-2" grid pattern as a guide. Roast all day in a 350 degree oven, until it falls apart to the touch. Chop large chunks of the cooked meat on a board with a cleaver or other large knife, until your preferred texture of sized pieces is achieved. Sprinkle sauce liberally. Finish cooking by warming chopped meat in a cast-iron skillet on low heat for 10-15 minutes.
