Next, having provided the utensils, good “stock” of various kinds should be kept constantly on hand, regulating the quantity prepared at one time by the state of the weather and the size of your family. In summer, in a cool cellar, it will keep, by frequent scalding, several days. In winter it is safe to keep it much longer, only, like everything else, it requires to be looked after carefully. Few soups can be of the best quality without a strong _stock_ to start with. _Liebig’s Extracts of Meat_ answers very well for a substitute, but is better used in connection with the stock. Every bit of meat which is left over, that cannot be satisfactorily employed otherwise, should go at once into the _stock-pot_ or _digester_. Bones, after carving from them all the meat that can be advantageously secured, must be well cracked and added to the other pieces. The vessel should be always near, ready to receive any stray morsel. When enough is collected to make a good quantity of stock, put cold water to the pieces; for the juices, which are what you desire to obtain, are much more readily extracted in cold water than in hot. On the contrary, meats that are to be boiled for table use should always be put into _boiling_ water, which closes the outer surfaces instantly, thus retaining the juices. When the water is added, set the digester over a moderate fire, where the contents will not boil rapidly, only simmer. After it begins to boil, add salt and pepper. Opinions differ as to the length of time needed in the preparation of good stock; but it is generally allowed to simmer most of the day, which is too long, and it thereby becomes muddy. We think a few hours’ boiling will extract all the juice, and make better stock than longer. Remember that stock should have more salt, pepper, and seasoning than would be desirable in the soup to be made from it. When done, strain it into a large stone pot, kept for that purpose exclusively, and cover closely till morning, when the fat will all rise to the top and harden, and should then be removed. Never allow stock to remain in the stock-pot or digester overnight; for, even when there is no copper to render it unsafe, it will assuredly taste of the iron, and the flavor be very greatly injured by it.
