The secret of success in this recipe is to leave the lamb to cook on a very low heat. Serve this springtime dish with plenty of bread to mop up the sauce.
Baking the lamb, rather than roasting, gives it a different texture and taste. Cooking on the bone stops the muscles in the leg retracting and squeezing out the moisture, and combined with the effects of the steam generated inside the salt crust, and the salt absorbed during cooking, this lamb is incredibly moist and tender. Serve with salsa verde, or mint sauce if you prefer.
