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.
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.
If you don't want to drink the broth immediately or want to save it for future use, you can freeze it in ice cube trays. Next up, fish broth- finally, a use for fish heads!
Thanks for posting the science behind the broth Kat! I'm so glad you made it, well worth the time!
ReplyDeleteYeah, I got a little carried away, but once you start reading about stuff like this, you just find more and more and more....
ReplyDeleteThe broth is yummy, but the disentigrated chicken was pretty gross. I made Tommy sift through the cartilage, bones, and skin!
