Place sponge cake on a baking sheet. Make meringue with egg whites and sugar. Pipe a border of meringue around the top edge of the sponge cake, and dry off in a very cool oven (265 ° F., Gas ½). Do not allow meringue to colour. Place a thick layer of macaroons or ratafias on top of the cake and soak well with the sherry for at least 1 hr. Avoid touching the meringue with sherry, otherwise it may crumble. Pile whipped cream on top and decorate with cherries and angelica.
