this is favorite rib sauce!!, I just copied it from amazingribs.com.

Yield. 1 quart.
Preparation time. 15 minutes
Ingredients
3 cups brown sugar
3/4 cup prepared yellow ballpark mustard
3/4 cup cider vinegar
Option. 1 teaspoon salt. I just think it makes a great sauce even better.Option. 1 1/2 teaspoon hot pepper sauce. Ditto.
Option. 3 tablespoons of your favorite rub adds a layer of complexity.
Option. 3 tablespoons of butter will add richness and depth.
Option. Jack Waiboer of Charleston, a champion competition cook and teacher of cue, says that substituting Southern Comfort for half the vinegar is a really nice thing.
Do this
1) Whisk all the ingredients together thoroughly in a cold saucepan. Heat gently over medium heat, stirring frequently until the sugar and mustard are dissolved completely, about 4 minutes. If it starts to boil, turn it down immediately. Try it first without the hot pepper sauce and butter options.
2) Here's how to use it, in Danny's own words: "The instant the ribs are pulled from the pit, coat them with a generous brushing of warm glaze. If you pull the ribs, chase the dog, talk to your buddy for a couple of minutes, then try and apply the glaze, you've waited too long." You can also serve it as a dipping sauce, warm, at tableside.
