I'll be smoking competition style spare ribs tomorrow. I'm gonna trim them down St. Louis style then I'll be rubbing it with my own home made rib rub. Using the 3-2-1 method and adding butter, brown sugar, honey, and tiger sauce when I foil them. I might use a chipotle BBQ sauce to finish them up with a nice glaze.
I bought the Kosmos KCBC Competition videos, where they show their exact process for their competition cooks of chicken, ribs, brisket, and pork butt. For ribs, they use the honey and brown sugar foil wrap after 2-3 hours, with apple juice as well. But he does something I've never seen anyone do with pork spare ribs: he wet brines them in the refrigerator for a few hours before applying rub.
Johnny Trigg also uses honey, brown sugar, and Parkay squeezable mid-cook on his ribs. And he's known as the "Godfather of BBQ", with ribs being his specialty.
So I figured I would see much of the same at Myron Mixon's BBQ school back in November, but I was surprised. For ribs, he does not use honey, brown sugar, or anything else as an additive mid-cook. His rub and finishing sauce is a bit sweet though, with some honey and brown sugar.
