I am doing my very first smoke this weekend on a 4lb pork shoulder. I know that the general thing logic is that it is done when it is done and that cook times can vary depending upon many factors. However, i have also heard a general rule of thumb of 1-1.5 hours of cook time per pound of meat. The shoulder will be the only thing in the smoker, so, realistically, is 6 hoursish a good timeframe to shoot for or am i looking at longer?
The reason I am asking is, my father-in-law, who uses a charcoal smoker says that he would probably smoke a pork shoulder for at least 12 hours. To me that seems long for a 4 pounder. Just trying to get some general advice. Thanks!
