I'm doing a pork shoulder (4.5 lbs) and had it on the smoker at 225 for 7.5 hours and it is only at 155 degrees? I have just wrapped it and put it in the oven at 250 - is this a good plan ? Any idea how long to get to 190 or 200 ? I had expected about 1.5 hours / lb so what did I do wrong? (I had out on counter for 1 hour before starting on smoker even prestarted smoker 1/2 before putting on ?
