Admittedly, being from up north, I know nothing about southern bbq. I made pulled pork for dinner tonight, and followed a recipe for Cider Vinegar BBQ sauce by Tyler Florence. It called for more mustard than ketchup, and is very tangy. Is this right? It's light in color and somewhat sweet, but very vinegar-y. It's unlike any commercial sauce I've ever had. (I usually buy Sweet Baby Ray's). It tastes ok to me, but I'm not exactly sure if it tastes like it is supposed to taste....
