If you've ever wondered why soups and sauces taste so good at restaurants, homemade stock may be the answer. This homemade stock recipe starts with two leftover roasted chicken carcasses. If you don't have two ready at once, freeze one and save it until you roast another chicken. Simmering the bones with herbs and veggies makes a virtually sodium-and calorie-free broth that has a deep, delicious flavor.
