"[Photographs: J. Kenji Lopez-Alt] Slow-roasted boneless leg of lamb comes out extra tender with a crisp, well-browned crust and juicy pink meat flavored with garlic, rosemary, and lemon zest. Why this recipe works: * Cooking at very low temperatures followed by a blast at high heat creates the ultimate contrast with pink meat that extends from edge to edge and a crisp brown crust. It also enhances tenderness. * Par-cooking a rub made with garlic, rosemary, lemon zest, and anchovies ensures that raw, steamed flavors don't last. * Anchovies in the marinade bring out the meatiness of the lamb without overwhelming with any kind of fishy aroma. * Note: Use any leftover cooked lamb in these Lamb Sandwiches with Tapenade Mayo, Watercress, and Caciocavallo Cheese.
