Smoked two (2) ~4lb. boston butts in my MES @ 225 for 7 hours and achieved very little if any bark. The day before I put on mustard and used Billy Bones B.B.Q rub, and wrapped them in glad clear cling wrap and put in fridge overnight. The next morning (6am) pulled them out of fridge while heating up smoker to get to close to room temp, and then put them in the smoker. Added apple wood chips every ~45 minutes. While smoking, I opened the door maybe twice for a quick look, then closed quickly, but that was about it. After 7 hours of smoking I had to wrap in tin foil to get past the stall, cause dinner time was coming quickly. So at the 7 hour mark wrapped in tin foil, turned up the heat and cook for another 3 hours till the IT read 200 and pulled them and sat in cooler for 30 minutes wrapped in towels. the PP absolutely fell apart and tasted good, but looking for more bark. didn't see much of a smoke ring either, just everything brown color. Please help what am I doing wrong? I thought 7 hours would produce alot of bark. Thanks in advance for any suggestions!!!!
