In making sauces great care should be taken to have the saucepans scrupulously clean and only granite-ware or porcelain-lined saucepans should be used, especially where there is any acid as in tomatoes or pickles. Never use an iron spider except for browning butter and flour together as they will not brown in a saucepan.
Take any kinds of vegetables convenient, such as parsnips, celery, carrots, turnips, green pepper, onion, leek, parsley, celery tops, celery root, Jerusalem artichokes, a bay leaf, two cloves, two allspice, and cook in water until tender; strain, pressing all from the vegetables. The water Jerusalem artichokes are boiled in is valuable for sauces. The liquid from canned peas is also excellent. Care must be taken in putting the vegetables together not to let any one predominate, turnip especially, as it makes a sauce very bitter.
