South Carolina Mustard Barbecue Sauce

South Carolina Barbecue Sauce


  • 1 cup prepared yellow mustard
  • 3/4 cup light brown sugar
  • 3/4 cup cider vinegar
  • 1/4 cup water
  • 2 tablespoons chili powder
  • 1 teaspoon black pepper
  • 1 teaspoon white pepper
  • 1/4 teaspoon cayenne pepper
  • 1/2 teaspoon soy sauce or Worcestershire sauce
  • 2 tablespoons butter
  • 1 tablespoon liquid smoke

Stir together all ingredients except the soy sauce, butter and liquid smoke in a heavy-bottomed saucepan. Simmer 30 minutes, stirring frequently to prevent scorching.  Add the soy sauce, butter and liquid smoke and stir well.  Return to a simmer over low heat and cook another 10 minutes, stirring often.  Cool to room temperature before transferring to a jar or squeeze bottle.  Store, tightly lidded, in the refrigerator.
