Girl I never knew how to make my own but I kick mine up a notch
I usually use Kraft's hickory smoke sauce then add Lea & Perrins, mustard, and a pinch of sugar. I know it sounds WAYYYYYY off but it's really good. When I can find it I also add in a little Open Pit sauce. The combo changes the falvor to the point when people ask where in the world I found such a great sauce....I tell 'em it was a secret family recipe!
