Noodle Soup

Beat well the yolks of four eggs in two tablespoonfuls of water and one saltspoonful
of salt, whip the white of one egg separately, add it to the rest and sift in
gradually, stirring at the same time, a sufficient quantity of finely sifted flour to make
a stiff paste. When quite smooth lay the paste on a floured board and roll out very
thinly. Cut the paste into diamond-shaped pieces, put them on a cloth and keep
them in a warm place until dry. Prepare some nicely flavored clear soup and when
it is boiling very fast throw in the pieces of paste and boil for ten to fifteen minutes.
Pour the soup in a soup tureen and serve while very hot, with a plate of Parmesan
cheese.
