A handbook of invalid cooking

by Mary A. Boland

Although mock-bisque soup is better made with fresh tomatoes, the canned fruit may be used, with the precaution that it be allowed to stew only just long enough to soften it through, for long boiling develops in it a very strong acid. When the tomatoes are soft, strain them through a soup-strainer, or other coarse wire strainer, until there is nothing left but the seeds. Measure a pint of the liquid, add the soda, salt, and pepper, and set it on the stove to heat slowly. Meanwhile make a white sauce with one tablespoon of butter, one of flour, and a pint of milk, according to the rule on [page 130]. Add this sauce to the tomato, strain all into a double boiler, return to the fire, and serve as soon as it becomes steaming hot.

If fresh tomatoes can be obtained, wash and wipe them, cut out the green part near the stem, divide them into small pieces without taking off the skins, and stew without water until the fruit is just soft enough to mash. If the tomatoes are fully ripe and carefully cooked, they will not require the soda, but when soda is necessary, fresh tomatoes need only half the amount used for canned fruit.

This is an appetizing and delicate soup, and may be freely used by most invalids.

POTATO SOUP

3 Medium-sized potatoes.
1 Teaspoon of chopped onion.
2 Saltspoons of celery-salt, or 3 stalks of celery.
1 Teaspoon of salt.
A little white pepper.
A speck of cayenne.
1 Teaspoon of flour.
2 Teaspoons of butter.
1 Pint of milk.

Pare and boil the potatoes. Cook the onion and celery in the milk, with which make a white sauce with the flour and butter. When the potatoes are done, drain off the water and dry them over the fire by moving the pan back and forth on the stove to keep them from sticking. Then, without removing the pan from the fire, mash them thoroughly with a potato-masher, and put in the sauce, pepper, cayenne, and salt; strain all through a soup-strainer, and if the consistency be not perfectly smooth and even, strain it again. Put it into a double boiler, set back on the stove, and when hot it is ready to serve. If the soup seems very thick, add a little more milk, for some potatoes are drier than others, and will consequently absorb more moisture. It should be like a thin purée.

This soup may be varied by using a quart instead of a pint of milk, and the whites of two eggs well beaten, the latter to be added just two minutes before it is removed from the fire, which will be sufficient time for the egg to cook. Care should be taken not to allow the egg to harden, or the soup will have a curdled appearance.

CREAM-OF-CELERY SOUP

1 Head of celery.
1 Pint of water.
1 Pint of milk.
1 Tablespoon of butter.
1 Tablespoon of flour.
½ Teaspoon of salt.
½ Saltspoon of white pepper.

Wash and scrape the celery, cut it into half-inch pieces, put it into the pint of boiling water, and cook until it is very soft. When done mash it in the water in which it was boiled, and add the salt and pepper. Cook the onion in the milk, and with it make a white sauce with the butter and flour; add this to the celery, and strain it through a soup-strainer, pressing and mashing with the back of a spoon until all but a few tough fibers of the celery are squeezed through. Return the soup, in a double boiler, to the fire, and heat it until it is steaming, when it is ready to serve.
