I started an 8.5 LB butt last night @ 8:30.
S. Florida, over night temp in the mid 70's
hickory and cherry.
smoker temp in the 225 range.
At 11:30 it was close to 140. (don't remember for sure. It was past rum:30) Dog woke me up @ 2:30 so I went to check. It was 151. Threw more wood on and back to bed. Got up @ 6:30 it was 171. Had to go to work and I did not want it in the smoker while not home. Oven set @ 225, into the oven NOT FOILED. Oven probe fluctuated between 210 and 220. Once in the oven the meat temp dropped to 165. I should have pre-heated the oven to 250. It stalled @ 165 for 3 hours. (wife came home and checked it) I added a second probe when I got home to make sure. @ 2:00 they were 174 and 183. I know they are both off a couple degrees, and I always pick a temp in between their readings.
Oven is riding @ 235. I set it @ 240. It is now 4:30 p.m., 16 hours later and the two meat probes read 189 and 195.
It's not done until the meat says it's done.
