I was fooling around today, not like I don't anything better to do, and I made a bar-b-q sauce using Dr. Pepper, Molasses, Ketchup, lemon, spices, this and that and a splash of Jim's finishing sauce (don't ask why). I was curious as to how long this can be stored and left in the fridge and what do commercial companies (Jim) use to make it last longer? Thanks, Dave
