Ultimate slow-roasted lamb: 12-hour Lamb Shoulder

Recipe video above. A 3-hour lamb shoulder is great. A 12-hour lamb shoulder is better! The meat is even more succulent because a lower cooking temperature means less moisture loss, and better flavour infusion from the rub. The sauce is a Lamb Jus made using the braising juices so it has phenomenal flavour. Don't be intimidated, it's simple and no more difficult to make than gravy!This is an excellent make-ahead recipe for gatherings. Why? Because you can make up to 4 shoulders in one standard oven. And the room for error is also almost nil; it's almost entirely hands-off cooking that magically takes care of itself overnight. Most importantly, the meat is so juicy it reheats 100% perfectly. I cook it overnight and reheat to serve that evening.About scaling up: 2 shoulders can be cooked in one large pan with no change to cook time. 4 shoulders (2 lambs in 2 pans, on 2 shelves) takes about 14 to 15 hours.
