Recipe: Grandmothers Sauce

CREAM together a cupful of sifted sugar and half a cupful of butter, add a teaspoonful of ground cinnamon and an egg well beaten. Boil a teacupful of milk and turn it, boiling hot, over the mixture slowly, stirring all the time; this will cook the egg smoothly. It may be served cold or hot.
