First attempt at HH spares on the WSM...and the first time I didn't use water in the pan. Slathered in mustard the night before and seasoned with Smokin' Guns Sweet Heat the night before, and again the following morning while the WSM was coming up to temperature. Smoked with apple and hickory at 275 degrees for 4 hours, using my DigiQ2. The only time that I opened the lid was to apply some SBR's honey barbecue to one slab 30 minutes prior to pulling them. Thought we'd be eating at 2:00, but I was informed that it would be 4:00 after the ribs were already smoking. Ended up pulling, foiling, and placing them in a cooler for 2 hours. Overall, some of the best (if not the best) ribs that I've ever made. Pulled cleanly off the bone, but not as moist as they usually are when I go 3-2-1. Unsure if this is due to them being held in the cooler. I definitely think that I'm on the road to being a "no water in the pan convert", but I'll hold judgement on that until my next pork butt cook (w/out water in the pan).
