Simmer for a few hours until it thickens.

I dont think this would make enough for a large amount of meat for a pot luck.
I make the sauce in very large batches at first I used to times the recipe x 5 but as my kids would want some I have since started making it with the vary large cans of ketchup I get at Sams. Its also much cheaper to buy it that way.

1 can ketchup (approx 12 cups)
3 cups apple cider vinegar
2 cups Dark Brown sugar
2 cups worcestershire
12 teaspoons of liquid smoke= 1/4 cup
OPT: 4-6 teaspoons cayenne pepper (to taste)
