I started 2, 7-1/2 lb boneless shoulders at 9 this morning. Smoker temp has been consistently chugging at 220-240 all day. I'm 12+ hours in and I'm not even close to being done. Both shoulders are at around 155 IT...climbing very slowly, I'm guessing, due to the very cold temps outside. I really don't feel like staying up very late......but I don't know what to do. Can I crank the heat to speed things up? I don't want dry PP even though I will still use a finishing sauce. Please help. I'm not sure what to do.
