We just finished consuming my first try at smoking baby backs!! They were delicious, all guests really enjoyed them!! I started with the 321 method and then added an extra hour because they weren't pulling back on the bone as I thought they should! Even with an extra hour, the bones were only out about 1/4", but everyone was waiting to test my smoking expertise so we ate PIG!! As mentioned, guest loved them, but I wasn't totally satisfied. The MES 30 performed flawlessly if I could believe the temp readings. I smoked 3 racks , for three hours naked, then 2 hours wrapped with brown sugar and honey, and then 1 hour with some BABY RAYS!! After the last hour, I still didn't have much bone exposed so I left them in for another hour. I was not trying for fall off the bone but I thought they could have been a little looser on the bone. Why didn't I have more bone after 7 hours?? Why wasn't the meat loose on the bone?? Maybe I'm being to Picky?? I did have lots of smoke, but had to load the feeder every 45 minutes!
