Add to NC's BBQ: Cheerwine, Cherry-Lemon Sundrop, RC cola, moon pies, fried chicken, liver pudding/liver mush -- same thing but goes by two names, pecan pie, Red Velvet cake, buttermilk biscuits, country ham & red eye gravy, Brunswick stew, fried seafood on the coast . . . and let's not neglect sweet tea.
Note that liver mush is made from pork products -- not pork and fried chicken.
BBQ is absolutely the quintessential NC food. For y'all Yankees, when we say BBQ, we mean pulled pork. I know y'all say you're BBQing when you're cooking out hamburgers and hot dogs -- for us, BBQ is a noun, whereas for y'all it's a verb. Specifically, Lexington style BBQ with a vinegar-based sauce (as opposed to a tomato-based sauce).
