After many nights of just sitting and watching the controller cycle, I finally put some food on last night.
I get a nice steady blue smoke in the 200-220 range at my current settings. So I cooked these for a couple hours at 200. Then a couple more hours at 250-275. Wrapped at some point for about 30 minutes.
I only had one rib, but they were delicious. I've always been a fan of pellet cooked ribs.
