Smoking the Pork Butt: Preheat Smoker Grill to 170 degrees F. Cooking at a low temperature will make the wood smoke more. Place the prepared pork butt, in the roasting pan, in the pre-heated smoker and close the smoker lid. Smoke the pork for 3 hours. The pork butt roast, also called the Boston butt, comes from the upper shoulder of the hog. Purchasing Pork Butt Roast: The pork butt makes the best sandwich meat (such as Pulled Pork Sandwiches and Sliders). Pork Butts can weigh 4 to 14 pounds and usually have a shoulder blade bone in them.
