In Northern Alabama, there is only one kind of bar-b-q sauce and that's "white sauce". A creamy mayonnaise base spiked with vinegar and black pepper, this hyper-regional sauce hailing from Morgan County, Alabama provides both a cooling creaminess and a tangy spice. Brush Jim'N Nicks Bar-B-Q Morgan Co. White Sauce on freshly smoked or grilled meats, slather it on sandwiches or use as a dipping sauce.
