SWISS LENTIL SOUP

Put lentils to cook in a large quantity of boiling water; boil rapidly a short time, then simmer without stirring. When they begin to get tender and are yet quite moist, slice an onion and press into the lentils until covered; keep the vessel over a slow, even fire, until the lentils are well dried out. The drying-out may be finished in the oven if the lentils are covered so that they will not harden on top. When well dried add a little boiling water and rub through a fine colander, removing the hulls. Into this pulp stir the browned flour. Beat till smooth, then add gradually enough boiling water to make of consistency of soup; salt, boil, and set where it will keep hot twenty minutes to an hour, to blend ingredients.
