Edith B. Cohen, The Economical Jewish Cook: A Modern Orthodox Recipe Book for Young Housekeepers
“ Every housewife should bear in mind that a stock-pot always on the fire is a great aid to economy. Any odd pieces, trimmings, cooked bones, the liquor in which meat or poultry has been boiled (commonly known as pot-liquor) , should be thrown in, and the pot kept about three parts full of water. When soup or gravy is required the stock should be well skimmed, and poured into a clean saucepan. ”
