Question: what is the difference between pork loin and pork sirloin?
Answer: Pork Top Loin Roasts are created by the butcher by tying two top loins together with the fat sides out. Pork Sirloin Roasts (a.k.a. loin pork roast, pork hipbone roast, pork loin end roast) are lean but less expensive than pork tenderloins.
