Yeppers he sure did use the Dr. Pooper marinate. Swear he had the grand prize winning brisket at Meridian the first year we ever cooked with him, Mz Suzie and Jack Hunter. We was supposed to be helpers but somebody winded up getting me tipsy on Ezra and coke..so wasnt much help
Only drawback on the brisket was it had not a smoke ring at all. Some folks claim you dont need one but I kindly disagree especially in that always tough crowd. If I was contemplating any type of marinate I would give it the TQ treatment before proceeding into the process. I googled up whut I believe is the authentic version and will post it over in the recipe section.
