OK, I just got a masterbuilt electric smoker. I pre-seasoned it and was excited to give smoking a try. I went out and got a 9.5 pound slab of pork butt. I seasoned it with some rub(forgot the mustard to help it stick). In looking at this site, I figured 1.5 hours per pound so I woke up at 3:00 this morning and set the smoker for 225 degrees and got it going. Now the problem is that when I checked on it around 9:00 the meat thermometer was already reading 170 degrees. I figured it would take at least 12 hours to reach that temp. I turned it down to give it more time, but I'm afraid the damage is already done and it won't be very tender and juicy. I thought I followed the directions pretty well, but I don't know what went wrong. I'd love some help! Should I just start at lower temps? Has anyone else had this kind of a problem? I'm hoping for a summer of smoking, but this isn't a good start.
