I am trying to think what sauce that was.................
was it Drapers BBQ. His BBQ sauce is excellent. He also has a most excellent all purpose rub and Moo'd Enhancer.
Shane Draper is now the pitmaster for Grilla Grills and if you go to their site you can get Grilla Grill sauces and rubs which are Shanes recipes.
Hope this is the one............
