Boiled Icing

1. 1 cup sugar.                                                                          3. 1/2 cup water.
2. 1/8 teaspoon cream of tartar.                                                4. White of one egg.
                                                                                                5. 1 teaspoon vanilla.


    Bring water and sugar slowly to boiling point. Add cream of tartar when it has boiled and continue boiling until it threads. Then pour on to the beaten egg. Beat until stiff and cold. Add vanilla and pour over the cake. Never stir the syrup after it has come to the boiling point as stirring makes it sugary.
