1.
What are the differences and similarities of making Brown stock from
the procedure on your hand out and from the 2 videos you watched?
      For me the difference in making brown stocks is that they don’t
sauté the chicken or the Mirepoix and just add it to bowl directly without
browning it and start it to a boil and as soon as it boils they simmer it for
3-5 hrs. All the stocks are made in a long process of simmering to create
an aromatic and very fragrant broth.
2. How does Making Brown Stock differ from making White Stock?
      One of the major difference is that in a brown stock the bones are
roasted/browned first as roasting gives the darker color to brown stock.
White stock is used as the base for veloute sauce and its derivative
sauces whereas brown stocks are used for making demi-glace and its
derivatives. The difference between making brown stock and making
white stock is browning the bones and mirepoix. Gelatin extracted from
bones is an important component of a good stock because it gives the
stock body. Bones to be used in brown stocks should be rinsed or
blanched before being used.
3. The Role of Acid in Making Stock
     Acid helps to break down the cartilage and other connective tissues
in bones, thus accelerating the formation of gelatin. The acid products
used are generally one or another of the following:
Tomato: Brown stocks use some sort of tomato product, usually tomato
paste, which also adds color and flavor to the stock.
Wine: White stock and chicken stock sometimes use white wine, and
fish stock almost always does.
One thing to remember is that acid reacts with aluminum cookware, so
use a stainless steel stockpot for making stock.
