TAKE the whites of twenty-four eggs, and a pound of double-refined sugar beat and sifted fine, mix both together in a deep earthen pan, and with a whisk will it well for two or three hours together till it looks white and thick, then with a thin board or bundle of feathers spread it all over the top and sides of the cake; set it at a proper distance before a good clear fire, and keep turning it continually for fear of its changing colour; but a cool oven is best, and an hour will harden it. You may perfume the icing with what perfume you please.
