I have typically done my cooking on butts at 225 which works out to roughly 2 hours a pound. I have two 8 pound butts to get ready tomorrow afternoon and I am trying not to stay up all night. I have heard that if you take the dome temp to 275 it works out to 45 minutes a pound - is that right? Also, does it affect the cooking time if you have two 8 pound butts on the egg at the same time or does that matter? (I would assume not but not sure...). Thanks!!
