Today I'm doing the first boston butt on my new 18.5 WSM. Put two totaling about 18 lbs. last night at 10:30 figuring on taking them off at about 1PM. I tried to turn the one on the top grate at about 9:30 AM and it fell apart. Checked the temp and it's already at 200! Should I take them off and plan to reheat later?
