Well I have ben smoking for about 7 months now. I have smoked all sorts of things from Pork shoulders/loins tenderloins, ribs fish chicken turkey and a whole assortment of fatties. Now my first attempt at a pork shoulder took around 12 hours for a 9 pounder. Now I have smoked around 6 (9 pounders)since my first and it seems that now I average around 18-19 hours per shoulder. What is going on? I understand that all shoulders are different some take longer than others. But for me on my Brinkman electric NOW average time is 18-19 hours. I have checked the temp and my smoker putts along at around 230 degrees. So is this normal to take THIS long for a shoulder?
