Cubby's BBQ Sauce

Could be the best BBQ Sauce I've had to date.
Yield 1 Gallon
2oz olive oil
2 cups onion minced
4 T crushed garlic
1/2 can chipotles in adobo
4 T Ancho or Pasilla Chile powder
2 1/2 cups apple cider vinegar
4 cups ketchup
2 cups molasses
1/2 cup soy sauce
1 cup brown sugar
1 cup honey mustard
2 cups water
1 T cracked black pepper.

Heat the oil in a stainless steel saucepan and sweat off onion and garlic till soft and sweet. Add chile powder and chipotles and let bloom. Add cider vinegar and bring to a boil. Add the remaining ingredients and simmer for 30-45 mins. Pass through a food mill or china cap, cool and refriderate.
