Mixed Stock Recipe

Put the trimmings of your fresh meats and the bones and tough pieces left from roasts or broils into the soup pot with one quart of water to every two pounds of meat and bones. When it comes to a boil, skim and set back where it will simmer six hours; then add a bouquet of sweet herbs, one onion, six cloves and twelve pepper-corns to each gallon of stock. Cook two hours longer; strain and set in a cool place. In the morning skim off the fat. Keep in a very cool place. This can be used for common soups, sauces, and where stock is used in made dishes. It should always be kept on hand, as it really costs nothing but the labor (which is very little), and enters so often into the preparation of simple, yet toothsome, dishes.
