SPLIT CAKE INTO THIN LAYERS, spread with jam and half the apricot
puree, and sandwich back together. Cut into bars, about
1-by-2-inches, and pack into a 2-quart serving dish, arranging
oranges in and around cake. Pour Marsala over top, spread with
remaining apricot puree and cover with custard. Cover and chill 2
hours. Whip cream with sugar until stiff. Frost on top of trifle and
decorate with candied fruits, if desired.
