I have an 8 lb pork butt which was prepped with DM's Pork Butt Brine in the SI3. When I was trimming, there was a deep layer of connective tissue nearly separating the butt, so I placed the Auber PID temp probe in the bone end, being careful not to touch the bone. I had a Maverick handy so I stuck one probe in the other end.
It's currently stalled at 169 deg (9 1/2 hours) according to the Maverick. However, I noticed a 12 point difference in temp between the two ends of this small butt. Because I am using the Auber to automatically decrease the SI3 to 140 deg after an internal temp of 193, I felt I needed to move the probe from the bone end. While opening (I really didn't want to) I also placed my second Maverick probe back in the bone end.
To recap, I now have the Auber temp probe and a Maverick probe in one end (reading 169 and 170 deg - 1 degree difference) and a second Maverick probe in the bone end which is reading 156 deg. Should I go with the non bone end since this is in the range of the stall described by others?
