You have to be kidding. Vinegar? Forgive me, but that's quite disgusting (yes, I've been unfortunate enough to sample it). However, I'm sure it tastes fine depending on how much hooch has been consumed. To each his own, but the vinegar thing is quite disturbing to me and I know I am not alone on that thought.
Don't question my taste on BBQ. I born amd raised in in the heart of original BBQ country (SE VA/NE NC). There are several vinegar based BBQ sauces recipes on this thread that look top notch.
Now when it comes to baby back rids, I like more mustard/vinegar base blend, But ribs ain't BBQ. BBQ is chopped, minced, or pulled pig meat, plain and simple.
And any of these ketchup based stuff they sell in the stores are an affront to southern sensibilities and and insult to the pig it's placed upon.
If you like that stuff, ypu are obviously from Michigan or some other snow encrusted tundra and grew up eating salisbury steak.
