A couple more sauces to play with, such as they are.

Piedmont Barbecue Sauce
From the Piedmont of North Carolina. Not a Lexington sauce, but still from the Piedmont.

2 cups ketchup
2 cups water
1/2 cup cider vinegar
1 large onion, minced
1/3 cup turbinado sugar
1/3 cup molasses
1 tablespoon mustard powder
2 teaspoons chili powder
2 teaspoons garlic powder

Combine ingredients. Simmer for 30 minutes. Let cool and refrigerate. Best if made a day or two in advance.

Kansas City Barbecue Sauce
My take on the sweet classic sauces of KC.

2 cups water
3/4 cup honey
1 6-oz. can tomato paste
1/2 cup cider vinegar
3 tablespoons molasses
3 tablespoons turbinado sugar
1/2 teaspoon sea salt
1/2 teaspoon paprika
1/4 teaspoon onion powder
1/4 teaspoon garlic powder
1/4 teaspoon pepper

Combine all ingredients in a medium saucepan over high heat and whisk until smooth. Bring mixture to a boil, then reduce heat and simmer for 45 to 60 minutes or until mixture is thick. Cool, then transfer to a storage container and refrigerate overnight.
