I usually refer to this sauce as my daddy's, but he got the recipe from his brother, my uncle Elzie, who according to the story, got the recipe from a man who sold barbecue, but the man would only share this recipe and sell him the rub. (He would not share the rub recipe.) I have many fond memories of eating smoked brisket or cabrito at my dad's and topping it with this sauce. This is the original recipe, but daddy added more heat by increasing the cayenne. It would be great with a little fresh jalapeno as well.
