This sauce is so authentic South Carolinians will be thinking we stole the recipe (we didn't) we just know BBQ. If you think mustard doesn't belong in BBQ sauce, you'll change your mind after a taste of this! This sauce is tangy with a slight kick, vinegar cuts the mustard (we said that) and the other special spices kick it off just right. Try it on pulled pork, ribs, brisket, and chicken. You'll be glad you did!
