To a large wineglassful (say a glass for champagne wine) of new Madeira add the yolks only of two eggs. Put in a very clean enamel saucepan over the fire and stir in powdered sugar to your taste. Whisk it over the fire till it froths, but do not allow it even to simmer. Use for Genoese cakes and puddings.
