Potato Soup

Arrowroot and well flavored stock are the secrets to potato soup.

Boil in their skins about a dozen medium-sized potatoes, and when done, peel and pass them through a fine sieve. Put a lump of butter about the size of an egg in a saucepan, let it melt, and add a tablespoonful of arrowroot, and stir over the fire until well browned; then add the potatoes with as much well flavored stock as will be required for the soup; boil all together. When done, pour the soup into a soup tureen, and serve while hot with a plate of sippets of toast or croutons of fried bread.
