Chicken soup is a soup made from chicken, simmered in water, usually with various other ingredients. The classic chicken soup consists of a clear broth, often with pieces of chicken or vegetables; common additions are pasta, dumplings, or grains such as rice and barley. Chicken soup has acquired the reputation of a folk remedy for colds and influenza, and in many countries is considered a comfort food.
1. Collect a Chicken carcass, giblets, and bones to make a rich stock. The giblets must be very fresh, and the bones and carcass those of a Chicken prepared the same day, otherwise any meat on them will be hard and dry, and the marrow in the bones very stale. Crack the bones slightly to release more flavor.
2. Put the carcass, bones, and giblets in a large pan. Add the celery and, if you like, sliced leeks. Add the slivered garlic and cover with about 9 cups water. Bring to the boil and skim the scum off the surface. Season with salt and pepper, and squeeze the juice of 1 lemon into the pan. Simmer gently for about 1 hour. Remove the pan from the heat and discard all the bones, leaving only pieces of Chicken in the broth.
3. Add the zucchini, if using them, and cook for 15 minutes longer.
4. Adjust seasoning, adding more lemon juice if necessary. The soup should have a distinctly lemony tang. It is this and the taste of garlic which give it an Oriental flavor
5. Add cooked rice just before serving so as not to give it time to become sodden and mushy.
