A cottage roll is the top end of the shoulder, otherwise known as the shoulder butt and is cured in a brine. They are usually just the right size for a slow cooker and are available at most supermarkets. You can have this with cabbage or creamed corn & boiled potatoes. Serve a little hot mustard on the side. The cottage roll will shred instead of slice, just like pulled meat does. Delish!
