Chicken Bone Broth (Nourishing Traditions, pg 124)

Grandmother Knew Best

Science validates what our grandmothers knew. Rich homemade chicken broths help cure colds. Stock contains minerals in a form the body can absorb easily-not just calcium but also magnesium, phosphorus, silicon, sulphur and trace minerals. It contains the broken down material from cartilage and tendons--stuff like chondroitin sulphates and glucosamine, now sold as expensive supplements for arthritis and joint pain.

Fish stock, according to traditional lore, helps boys grow up into strong men, makes childbirth easy and cures fatigue. "Fish broth will cure anything," is another South American proverb. Broth and soup made with fishheads and carcasses provide iodine and thyroid-strengthening substances.

When broth is cooled, it congeals due to the presence of gelatin. The use of gelatin as a therapeutic agent goes back to the ancient Chinese. Gelatin was probably the first functional food, dating from the invention of the "digestor" by the Frenchman Papin in 1682. Papin's digestor consisted of an apparatus for cooking bones or meat with steam to extract the gelatin. Just as vitamins occupy the center of the stage in nutritional investigations today, so two hundred years ago gelatin held a position in the forefront of food research. Gelatin was universally acclaimed as a most nutritious foodstuff particularly by the French, who were seeking ways to feed their armies and vast numbers of homeless in Paris and other cities. Although gelatin is not a complete protein, containing only the amino acids arginine and glycine in large amounts, it acts as a protein sparer, helping the poor stretch a few morsels of meat into a complete meal. During the siege of Paris, when vegetables and meat were scarce, a doctor named Guerard put his patients on gelatin bouillon with some added fat and they survived in good health.

The French were the leaders in gelatin research, which continued up to the 1950s. Gelatin was found to be useful in the treatment of a long list of diseases including peptic ulcers, tuberculosis, diabetes, muscle diseases, infectious diseases, jaundice and cancer. Babies had fewer digestive problems when gelatin was added to their milk. The American researcher Francis Pottenger pointed out that as gelatin is a hydrophilic colloid, which means that it attracts and holds liquids, it facilitates digestion by attracting digestive juices to food in the gut. Even the epicures recognized that broth-based soup did more than please the taste buds. "Soup is a healthy, light, nourishing food" said Brillant-Savarin, "good for all of humanity; it pleases the stomach, stimulates the appetite and prepares the digestion."


PROJECT BONE BROTH

Start Time: 1:30PM, End Time: 8:00AM


Bone Broth at 10:11 PM

Chicken Stock

1 whole free-range chicken or 2 to 3 pounds of bony chicken parts, such as necks, backs, breastbones and wings*
gizzards from one chicken (optional)
2-4 chicken feet (optional)
4 quarts cold filtered water
2 tablespoons vinegar
1 large onion, coarsely chopped
2 carrots, peeled and coarsely chopped
3 celery stalks, coarsely chopped
1 bunch parsley

*Note: Farm-raised, free-range chickens give the best results. Many battery-raised chickens will not produce stock that gels.

If you are using a whole chicken, cut off the wings and remove the neck, fat glands and the gizzards from the cavity. Cut chicken parts into several pieces. (If you are using a whole chicken, remove the neck and wings and cut them into several pieces.) Place chicken or chicken pieces in a large stainless steel pot with water, vinegar and all vegetables except parsley. Let stand 30 minutes to 1 hour. Bring to a boil, and remove scum that rises to the top. Reduce heat, cover and simmer for 6 to 8 hours. The longer you cook the stock, the richer and more flavorful it will be. About 10 minutes before finishing the stock, add parsley. This will impart additional mineral ions to the broth.

Remove whole chicken or pieces with a slotted spoon. If you are using a whole chicken, let cool and remove chicken meat from the carcass. Reserve for other uses, such as chicken salads, enchiladas, sandwiches or curries. Strain the stock into a large bowl and reserve in your refrigerator until the fat rises to the top and congeals. Skim off this fat and reserve the stock in covered containers in your refrigerator or freezer.
