Potato Soup
Directions
Boil and mash three or four potatoes, one tablespoon of butter, one-half tablespoon of flour, and one teaspoon of chopped onion, letting the onion cook in the butter a few minutes before adding the flour. When this is cooked add to it a pint of milk, making a thin, white sauce. Add this to the mashed potato and pass the whole through a strainer. Return it to the fire for a few minutes to heat and blend it. Season it with salt and pepper. Sprinkle on the soup chopped parsley and a few croutons.
