Cut four slices of sponge cake about an inch thick and of an oval shape, but each slice smaller than the others. Spread a thick layer of apricot jam upon the first and largest slice, and then lay the next sized slice upon it; spread the second slice with apple marmalade, and cover with the third size, which is to be spread in like manner with strawberry jam, and covered with the smallest size. Press the top lightly with the hand, and with a sharp knife cut away the central part, so as to leave a wall about two inches and a half thick, which is to be trimmed outside. Mash up the part removed from the centre, with equal parts of white wine and brandy, sufficient to flavor, and stir in some thick custard, then pour into the center of the cake. Whip the whites of two eggs into a stiff froth, pour over the whole, heaping it well up in the centre, and shake sifted sugar thickly on, then place in a quick oven until the frosting is set. A few pieces of strawberry jam or any other preserve placed round the bottom of the dish, gives a finish* to the whole.
