Whole bone-in leg of lamb is as at home as a Sunday roast dinner as it is as the centerpiece dish of an elegant dinner party. We love it simply cooked on a bed of onions and garlic and rosemary, rubbed with fennel seeds, salt and pepper. It truly is magnificent. And then after your meal you can roast that bare bone in the oven more and then make a delicious, nutrient-dense bone broth.
