Boil a quart of milk, add a very little salt, and two tablespoonfuls
of rice or wheat flour wet in cold milk. Stir in smoothly, and let it
thicken in a vessel of boiling water, keeping the outer saucepan at a
hard boil for half an hour. Eat with butter and sugar, or with cream
and sugar. For invalids, or children who are suffering with summer
disorders, boil at least an hour, stirring very often.
