Recipe: Substitute for Cream in Coffee

Beat the white of an egg, put to it a small lump of butter and pour the COFFEE into it gradually, stirring it so that it will not curdle. It is difficult to distinguish this from fresh cream.

Many drop a tiny Piece of sweet butter into their cup of hot COFFEE as a substitute for cream.
