By nature, pulled pork needs to be made from a cut of pork that will become tender and basically fall apart after cooking. Pork butt and pork shoulder roasts fit the bill perfectly. These might also be labeled Boston butt or picnic shoulder. Pork butt and pork shoulder roasts are perfect all year-round. Roasts cook up super well in the slow-cooker which is an ideal tool to use in the summer time as well as in the busy winter months. Not only do they save you from heating up the oven, but they can also sit for awhile cooking dinner while you finish your daily business.
