GERMAN POTATO SOUP
The German potato soup is made by rubbing 6 or 8 well-boiled potatoes through a sieve together with enough of the water in which they were cooked to make sufficient soup, and adding 1 tablespoon of chopped chives (or shallot or onion), 1 teaspoon of chopped parsley, ½ cup of sour cream containing a little lemon juice, or, instead of sour cream, 1 tablespoon of reduced vinegar can be used, with ½ cup of fresh cream. Let simmer for fifteen minutes and serve very hot with croutons.
