This is my "house sauce", simple to make, not hot but has a little bite on the back end.
64 oz. ketchup (I use Hunt's)
3½ cup cider vinegar
3½ cup packed brown sugar
4 T worchestershire sauce
14 T BP Shaker (basicly a all-purpose rub I make, use your favorite rub)
10 pinches (or to taste) chipotle powder
Combine all ingredients and simmer for about 45 minutes or until to the consistency you want. Best when refrigerated overnight (at least) first.
