Wash, pare and grate raw potatoes. Strain but not too dry, and use
juice for soup or sauce. If juice is retained, a little more flour
will be needed for thickening. Grate and add the onions; add salt
and the egg. Beat well. Mix remaining ingredients and beat into
potatoes; mix well. Drop by spoonfuls into hot fat that is deep
enough to almost cover the cake. Brown on both sides. Drain on
absorbent paper. Serve with applesauce, if desired.
