Handpicked Nation - Have you ever eaten rack of lamb? A tasty, tender, roasted 4-bone rack of lamb. Have you ever thought about how many racks a butcher can cut from one lamb? Four, if it’s a big lamb. If a restaurant is anticipating selling 100 servings of rack of lamb over a weekend, they’ve bought racks cut from at least 25 lambs. It’s likely that the same restaurant will be selling specific cuts from other animals, such as pork and beef, alongside that lamb.
