Have my Dad's sauce recipe from our old place. Aggravating to make but everyone loves it.
I make my own sauce.
I have a recipe for my own bbq sauce and glaze. I don't like to give out my recipes in full, but i will say that i stick a lot to the basic (sugars, spices and tomato paste) and i add some homemade apple juice. For the glaze i add some Guinness. It took me a while to finally get them right, but everyone that tries them love them.
