I think there are as many BBQ's and sauces as there are those who prepare them. And I have yet to find one I didn't like. Here in Ga., though, we love our sauces to have at least some brown sugar in them. I use soy and Worcestershire sauce in mine as well, plus catsup or tomato sauce/paste, usually cider vinegar but any will do, a drop or two of liquid smoke (too much makes it sit heavy on the stomach), mustard, occasionally a mild sprinkling of taragon (try it & you'll like it if you like taragon), and whatever else appeals to me when I'm making it. Always use onion powder and garlic powder, too. Never made a bad one yet, and never really went by a recipe. A tiny taste test and adjustment of the mix keeps me straight. My wife is totally lost on BBQ sauces, so when she says we're out, I always get busy. Heating it all together helps blend the flavors and make a smoother tasting sauce. Simmering a bit thickens it up if you like a thick sauce. I doubt I'll live long enough to try all the things I want to try in making BBQ sauces, and if I have to smell the sweet aroma of pork being BBQ'd, I usually fall into the regimen described above. Never had any complaints, unless I put too much LA hot sauce, peppers (red or black) in it for their taste. My wife's a real pansy when it comes to anything "hot." So I usually just put black pepper or LA hot sauce on my meat, then the sauce, and mix it all together.
I can't even imagine a "bad" BBQ!
