Having opened a cocoa-nut, pare off the brown skin from the pieces, and wash them all in cold water. Then weigh three quarters of a pound, and grate it into a dish. Cut up half a pound of butter into half a pound of powdered loaf-sugar, and stir them together to a cream; add to them a glass of wine and rose water mixed. Beat the whites only, of twelve eggs, till they stand alone on the rods: and then stir the grated cocoa-nut and the beaten white of egg alternately into the butter and sugar; giving the whole a hard stirring at the last. Put the mixture into a buttered dish, lay puff paste round the flat edge, and bake it half an hour in a moderate oven. When cold, grate powdered sugar over it.
