My wife asked why one of the butts was mushy. She is my best/worst critic.
Out of four butts of different weights the two larger butts were a bit mushy. I noticed that even though the temp was at 195 they felt heavy and soft compared to the smaller ones.
After resting, I noticed that the largest butt had a lot more oil in the foil than the rest of them and it was the one that was at 199 when I took them off.
I tried to take them all off at the same time by averaging the temps between the top and bottom grate.
I guess the question is:
What is the best way to smoke a wsm load of butts ?
