Here’s What He Mixed Together: Worth Readin: It didn't happen overnight, but Rufus Teague's sauce has sure come a long way. From the ol pot he used to stir it in, to winning competitions all over the place, this sauce hasn't changed much. If he was still around there's no doubt he'd be tellin everybody within earshot of how he knew he had something with this recipe from day one.
