Okay chowhounders, I need your help. I've received a request for some good BBQ sauces for pork shoulder, preferably a variety of sauces. Any type, traditional barbecue, North Carolina vinegar, South Carolina mustard, Memphis, Kansas City, you name it. I don't need a recipe for the pork, I've got that covered, only for the sauce. Recipe can come from an online source or a cookbook (I can get my hands on it, whatever it is), doesn't matter, the only caveat is you have tried it personally and think its really good.
Any recommendations, oh masters of the BBQ?
