I put on a Tri Tip and smoked at 225 for awhile, maybe 30 min.. meat went on at 60 degrees.. It was thoroughly coated with rub... It began to climb in temp pretty rapidly, withen 40 min it was at 90 degrees?? Thermo never went over 250... I pulled it at 140 and it just didn't have a dark appearance to it. It cooked for 1:05 min... It was a nice medium rare.. Tasted fantastic. Just didn't Bark up like I wanted it too... It was a smaller piece of meat. Just over 2-1/2 lbs.. What could I have done to get the color and bark better..
