We call for lamb shoulder because it's tougher than other cuts and holds up well throughout the long cook time. If you can't find shoulder, use boneless leg of lamb in this slow-cooker butternut squash stew.
Multicooker Directions: In Step 1, transfer all of the browned lamb to the inner pot of a 6-quart multicooker, discarding the drippings in the skillet. In Step 2, stir the squash, onions, chickpeas, stock, curry powder, garlic, salt, and ginger into the lamb mixture in the pot. Lock the lid; turn Pressure Valve to "Venting." Cook on SLOW COOK [Normal] until the lamb is tender, about 7 hours. Turn off the cooker. Skim the fat from the surface of the cooking liquid. Stir in the coconut milk. With the lid off, press SAUTÉ [Normal]; cook uncovered, stirring often, until slightly reduced, about 30 minutes. Finish step 2.
