To the white of an unbeaten egg add one and one-fourth cups of pulverized sugar and stir until smooth. Add three drops of rose-water, ten of vanilla, and the juice of half a lemon. It will at once become very white, and will harden in five or six minutes.
PLAIN FROSTING
To one cup of confectioner's sugar add some liquid, either milk or water, to make it the right consistency to spread, flavor with vanilla. Instead of the water or milk, orange juice can be used. A little of the rind must be added. Lemon juice can be substituted in place of vanilla. Chocolate melted over hot water and added to the sugar and water makes a nice chocolate icing; flavor with vanilla.
ALMOND ICING
Take the whites of two eggs and one-half pound of sweet almonds, which should be blanched, dried and grated or pounded to a paste. Beat the whites of the eggs, add half a pound of confectioner's sugar, one tablespoon at a time, until all is used, and then add the almonds and a few drops of rosewater. Spread between or on top of cake. Put on thick, and when nearly dry cover with a plain icing. If the cakes are well dredged with a little flour after baking, and then carefully wiped before the icing is put on, it will not run and can be spread more smoothly. Put the frosting in the centre of the cake, dip a knife in cold water and spread from the centre toward the edge.
MOCHA FROSTING
One cup of pulverized sugar into which sift two dessertspoons of dry cocoa, two tablespoons of strong hot coffee in which is melted a piece of butter the size of a walnut. Beat well and add a little vanilla.
MARSHMALLOW FILLING
Melt one-half pound marshmallows over hot water, cook together one cup of sugar and one-quarter cup of cold water until it threads thoroughly. Beat up the white of an egg and syrup and mix, then add to the melted marshmallows and beat until creamy and cool. Can be used for cake filling or spread between two cookies.
