Superior Stock ~ The traditional Superior Stock is usually produced in quantity in
China, which is a long and stylized process.  When dining in a restaurant in
Peking, one can usually call for Superior Stock to be served as soup free of
charge.

1 chicken (about 3 pounds) ~ remove drumsticks and breast
set aside. Remove liver)
2 pounds pork
2 pounds spare ribs
3 pounds pork bones
1 pound ham
8 - 10 quarts of water
- - - - - - - - - - - - - - -
3 tbsp of fresh ginger slices,
1 large onion, quartered
3 garlic cloves, smashed

note:
1.  For easy removal later, you can put these into a small cheesecloth bag
2.  Do not add salt or MSG ~ these are added in the individual recipe.

Remove the breast meat and 2 drumsticks from a 3 pound chicken (remove and
discard liver), and boil the rest of the chicken for 15 minutes with 2 pounds pork,
2 pounds spare ribs, 2 pounds pork bones, and 1 pound of ham in 5 to 6 quarts
of water, skimming off all scum and extraneous matter.  Lift out the chicken and
pork, then the pork bones, and place them all in a bowl containing 2 quarts of
cold water.  After turning the chicken and bones around in the water, pour half of it
into the stock, in which the chicken, has been boiled.  The sudden coolness
of the water coagulates and precipitates more of the grease and impurities in the
stock, these can easily be skimmed off.  Before returning the chicken, pork, and
bones to the pan for a further period of simmering, pour a quarter of the now
augmented stock into a separate bowl to cool.   This cooling stock will be used
later on in the same way as the cold water was used to precipitate and coagulate
grease and impurities.  After the chicken, pork, etc. has been returned to the main
pot, bring the contents to boil and simmer gently for 1 hour.  The chicken, and
pork are again lifted out, and the cooled broth water poured into the pot, again
precipitating and coagulating more grease, impurities, and extraneous matter
which are again removed.     The above process is repeated twice more over a
period of 3 hours, after which the stock will have become stronger as well
as more purified.
The final phase of the preparation consists of some seasonings and double
clarification.  The seasoning is done by the addition of a small amount of ginger,
onion, and soy sauce (according to your own taste)  Chop the breast meat and
the meat from the drumsticks of the chicken, keeping them separate.  The
chopped darker drumstick meat is used for the first clarification, and the minced
white breast meat is used in the second clarification.  The clarification is
achieved in each case by simmering the minced chicken in the stock for 10 - 12
minutes, then straining it.  The important thing is not allowing the stock to come
to a full boil at any time, thus creating what is called a stewed stock.  The
simmering has to be kept very gentle throughout to produce clear stock.
For making larger quantities of this Superior Stock a duck, where available, can
be added to every 2 chickens used.  But only the chicken meat should be used
for clarification.
A fascinating and established way of conducting the process of clarification in
restaurants is to place only a quarter of the pot over the fire, and a filter at the
opposite side just below the surface of the stock.  Because of the heat, the stock
at the fire-end of the pot rises rapidly, carrying all the impurities with it.  As the
liquid reaches the top and pours over to the opposite end, the impurities are
caught by the filter.  As the process is circular and continuous, the stock
becomes progressively and increasingly purified; and within the 10 - 12 minutes
that the clarification is working, the stock will become crystal-clear.
For more clarification, refrigerate stock for about 1 hours or until well chilled.  Any
oil will have then moved to the top where it can be removed.  I use coffee filters
and pour the chilled stock through the filters...slowly.  Superior Stock can be
frozen for later use.    Superior Stock is essential in the preparation of soups and
sauces if these are to be of the highest quality.  Egg Flower Soup ~
