I tried the usual 3,2,1 with ribs and in fact, I think it was more like 2,2,0. After 2 hrs in foil, the bones just fell off and the meat was a bit mushy. So, I saw no reason to finish up with an additional hour. I smoked it all at 225 approx. I kept in foil in the fridge until party day then re-warmed. The meat ended up bing a bit on the tough side, in my opinion, which was surprising. I was expecting it to remain mushy. Any suggestions for how to do it correctly next time?
