You can buy all sorts of BBQ sauce at your local Kroger and lot's of it is pretty good. Most of it is pretty generic but I've yet to find any based on mustard or vinegar outside of a good BBQ house.

If you are up for a culinary adventure try this one on for size:

Carolina Style BBQ Sauce

Ingredients:

1 1/2 cup Yellow Mustard (French's or Heinze)

1/2 cup Brown Sugar

3/4 cup cider vinegar

3/4 cup beer (dark is best)

1 TBS Chili powder

1TEA black pepper

1TEA white pepper

1/2 TEA cayenne pepper

1 1/2 TEA Worcestershire Sauce

2 TBS Butter

1 1/2 TEA liquid smoke

1 TEA Louisiana Style hot sauce

Directions:

1. In a heavy non-reactive sauce pan, stir together the mustard, brown sugar, vinegar and beer. Season with chili powder, black, white and cayenne pepper. Whisk together and simmer over low heat for 20 minutes. Don't boil or you will scorch the sugar.

2. Mix in the Worcestershire, butter, and liquid smoke. Simmer for another 15 or 20 minutes. Season to taste with hot sauce.

3. Store in a Mason jar. Refrigerate overnight after cooling to allow flavors to mix.

The sauce has a spicy, tart taste that works well on pulled pork, brisket, chicken or sausage.
