Well my first set of ribs went on the UDS about five minutes ago. Started last night with prep and then application of rub. Using Jeff's "naked" rib rub. Went into fridge overnight. Pulled them out this morning to allow a few hours to get to room temp. Then on they went for the start of the 2-2-1 that I'm doing. I think that's correct since these are back ribs and not spare ribs(St. Louis style). Hopefully I've done everything right so far. I'll keep y'all posted. This post sent via carrier pigeon.
