POTATO SOUP
Wash 6 to 9 potatoes and put them in boiling water and boil them from twenty minutes to half an hour, the time depending on their size. Use 1 large onion quartered, with cloves stuck in it, and 2 pieces of celery (or ¼ teaspoon of celery salt or celery seed), some mace, 1 bay leaf, and 6 peppercorns, and put in a double boiler with 1 quart of milk, from which reserve 1 small half cup. Mix 1 tablespoon of flour with the reserved milk, and stir slowly into the milk when it boils, and let cook ten minutes longer. When the potatoes are done pour off the water, peel them and mash until light, then add to the boiling milk, stir well, season with salt and pepper, and rub all through a sieve. Return to double boiler, add 1 tablespoon of butter, 1 teaspoon of minced parsley, boil up once, and serve.
