Rock Cake
396. Three eggs, (the whites only.) Three-quarters of a pound of sugar, Three-quarters of a pound of sweet and bitter almonds.
Whisk the eggs very light and dry, then add gradually a tea spoonful of the sugar at a time. Beat it hard until all the sugar is in. Blanch the almonds, cut them in pieces about the size of a pea, mix them with the egg, drop them on sheets of white paper, and bake them in a cool oven.
