This week, Shea Hess dives into slow cooking and homemade barbecue.  Focusing on pork shoulder, she talks to local butcher Sara Bigelow from The Meat Hook about where to source the meat and tips for purchasing the proper amount. Then she travels to barbecue restaurant Fette Sau in Williamsburg, Brooklyn for a chat with owner Joe Carroll to learn his tips on slow-cooking pork shoulder and other meats at home. Finally she takes you into the kitchen for a pork shoulder slow roast that's easy enough for any home cook to tackle.
