I started smoking 4 pork butts at about 5:30 A.M. on Saturday. It was kind of chilly and windy so the smoker temps didn't make it above 200 very often but was almost always between 185 and 200. By 7:30 P.M. the meat was only at 150 give or take a little. I had other things I needed to take care of so I wrapped the butts in foil and they went into the frig overnight. About 11:30 A.M. on Sunday, they went into a 250 degree oven to finish. It took about 4 hours to get them back up to 150. Finally, at 12:30 A.M. the last butt reached 205. By my count that is about 23 hours of cooking (excluding the time to get back up to 150 in the oven). This seems like an unusually long time for butts to get done. They were roughly 7-9 pounds each. Any thoughts?
