In a large saucepan
over medium heat, mix together the ketchup, tomato sauce, brown sugar,
wine vinegar, molasses, liquid smoke and butter. Season with garlic
powder, onion powder, chili powder, paprika, celery seed, cinnamon,
cayenne, salt and pepper.
Reduce heat to low, and
simmer for up to 20 minutes. For thicker sauce, simmer longer, and for
thinner, less time is needed. Sauce can also be thinned using a bit of
water if necessary. Brush sauce onto any kind of meat during the last 10
minutes of cooking.
