Basic Carolina-Style Barbecue Sauce

This tangy mustard-based sauce brings out the very best in chicken or pork. Makes 4-1/2 cups-enough for approximately 8 pounds of meat.

2 cups yellow mustard
1-1/2 cups cider vinegar
1 cup sugar
1/2 cup lt. brown sugar
1/2 cup water
4 tbsp butter, margarine, or olive oil
3 tbsp chili powder
2 tsp black pepper or pepper medley
2 tsp liquid smoke hickory
1 tsp soy sauce
1 tsp Worcestershire sauce
1/2 tsp cayenne or red pepper

In a medium pot, mix everything except butter, soy sauce, and liquid smoke. Simmer for 30 minutes, then add the remaining ingredients. Simmer for 10 more minutes. After cooling, store in glass jars and keep refrigerated. Will last for several weeks.
