Nigella’s Slow Cooked Lamb Shoulder is a low-and-slow cooking method that results in incredibly tender, succulent lamb. Cooked in the oven with aromatic herbs, garlic, and wine, the lamb is allowed to baste in its own juices, resulting in a dish that’s packed with flavor and beautifully moist. It’s a dish that requires little hands-on time, but the end result is nothing short of impressive.
