I usually put 1 wireless probe in at the start, then no spot probing with another thermometer until the wireless goes past 140. I have wondered about the merits of a one-time pink-salt (nitrate) steralization dip for the first probe. Thoughts?
I usually blast by 140 in 4, but last night I put two 12.5lb-trimmed briskets into the WSM, it was 39F outside, and I held back and only filled the ring to 75% full. I went to bed after 3 hours total with an IT of 131 and airT of 246, and after 7:45 hours total I woke to an IT of 154 and airT of 192. The charcoal was nearly gone :-( I think I'm safe, but I hate even having a doubt. I carefully placed some additional briquettes into the WSM, but it never recovered, so I pulled and foiled at 150 IT.
