Paul Kirk's Texas-Style Brisket Bbq Sauce

Grrrrrgh!
Course : BBQ Sauce
From: HungryMonster.com
Serves: 6
 

Ingredients:

1/2 cup butter -- 1 stick
2 cups minced onion
4 cloves garlic -- pressed
2 cups ketchup
2 cups chili sauce
1 cup brown sugar -- packed
1/2 cup fresh lemon juice
1/4 cup red wine vinegar
2 tablespoons Worcestershire sauce
1 tablespoon liquid smoke
1 tablespoon prepared yellow mustard
2 teaspoons salt
2 teaspoons black pepper
1 teaspoon cayenne
 

Preparation:

Heat the butter in a large non-reactive saucepan over medium-high heat. Add the onions and garlic and sauté' for 2 to 3 minutes, until just soft. Pour in the ketchup and chili sauce, and blend in well. Add the rest of the ingredients. Bring the mixture to a boil, then reduce the heat and simmer for 30 to 45 minutes, stirring occasionally. This sauce will keep for up to 2 weeks in an airtight jar in the refrigerator. Begin applying the sauce warm to barbecuing brisket, about 30 minutes before the end of the cooking time. My Notes: In place of the chili sauce I used some fresh roasted New Mexican red chiles pureed in the food processor with a little water. I didn't use the liquid smoke because I don't like the taste of it and the meat had plenty of smoke flavor on its own. While this is not a real sweet sauce, I would still use a little less sugar next ti
