Tiramisu

Serves 6-8. Mix half the rum with the brandy and coffee in a shallow plate. Dip both sides of the sponge fingers in the brew and place in a shallow pudding dish. Pour over any excess mixture. Wish the mascarpone cheese with the egg yolks and sifted icing sugar, then add the remaining rum. Beat the egg whites until stiff, stir a spoonful into the mascarpone mixture, then fold in the rest. Spoon over the sponge fingers,sprinkle with the cocoa powder, cover with cling film and refrigerate overnight
