You nailed it.
The bark is to die for!
Unlike chef Jimmy, I am averaging 80 - 90 minutes a pound on a stickburner' (unfoiled), slightly less time unfoiled, at a temps around 240°.
I have experimented with foiling to help it through the stall and the bark has not been affected.
Bigger butts seem to take more time per/lb, for me anyhow.
Question to Jimmy, are you getting the same time per/lb on all of your smokers?
