The Shacks Barbecue Sauce (Little Rock) - cooking recipe

Ingredients

6 tablespoons salt
6 tablespoons sugar
6 tablespoons black pepper
6 tablespoons chili powder
4 cups ketchup
4 cups white vinegar
4 cups water
1 large onion, finely diced

Preparation

Combine first four ingredients and set aside. In large saucepan, combine combine ketchup, vinegar, water and onion. Stir in dry mixture. Bring to a rolling boil, reduce heat and cook uncovered 1 1/4 hours, stirring every ten minutes.
The mixture will reduce to almost half, about 55 ounces. Pour into sterilized jars and let rest for a few days. When I make this, I just pour the mixture into the empty ketchup bottles and store in the refrigerator.
