Put six whole eggs into an earthen pan with half a pound of sugar, upon which you have previously rubbed the rind of a lemon, stand the pan in very hot water, keeping its contents well mixed until becoming rather warm, when take it from the water, continuing to whisk until quite cold and thickish, when stir in gently half a pound of sifted flour; have ready buttered, and dusted with sugar, about a dozen small sponge-cake tins, put a tablespoonful of the mixture into each, shake sugar over, and bake them in a moderate oven.
