The fat . Usually they will give it to you. Sometimes the beef is packaged as beef suit. As for the pork fat, just ask, especialy when they're trimming chops. When the whole boneless pork loin goes on sale I'll pick one up for smoked chops or canadian bacon or just to use as a roast, then I save the trimmings for latter use. I've read that some people add ground bacon to their venison, though I haven't tried it yet. ps. when adding the fat be sure it is really cold. Actually all the meat should be very cold, 34-38 degrees Hope this helps.
