A Course of Lectures on the Principles of Domestic Economy and Cookery

from one side, and very gently, then when you strain it after it is done it already will be as clear as most clear soup. After it has been strained, to-morrow, we shall clarify it in order to show the process, which is very simple. Then it will be what is called on hotel bills of fare clear soup. After the vegetables have been added let the stock boil for at least two hours. In that length of time the flavor of the vegetables and the nourishment from the meat will be extracted, but not the gelatine from the bones. It is the gelatine in the bones which makes broth or stock jelly when it is cold; in order to extract the gelatine it is necessary to boil the soup meat and bones at least five hours. The soup can be strained at the end of two hours, or boiled five or six hours, keeping it covered so that none of it wastes or evaporates. When the soup is boiled, strain it; use an earthen bowl or jar; set a colander in it, and lay a towel folded twice in the colander, having the colander either over the bowl or jar; pour the soup into the towel, and let it run through without squeezing, because if you squeeze the towel you will force small particles of scum through, and thus cloud the soup. After the soup has run through the towel let it cool; do not cover it while it is cooling unless you are afraid of flies or insects getting into it; in that case cover it with a sieve. If you cover it with a solid earthen cover or plate the steam arising from the soup will condense on the under part of the cover and fall back into the soup; if the weather is warm, or if it is a close, rainy day, the steam condensed falling back into the warm soup will cause it to sour. For this reason when you put away a dish of meat or vegetables after dinner do not cover them until
