Dice the cake bases, drizzle with orange juice and sherry. Thaw and drain the fruits, sweeten with vanilla sugar. Boil a pudding with the milk, let it cool down a little (stir regularly so that no skin develops), stir in the crème fraîche and sour cream, add sugar if necessary. Whip the cream until stiff.
In a large glass bowl, layer in the following order: 1 layer of cake, 1 layer of almonds, 1 layer of fruit, 1 layer of pudding, 1 layer of cream. Repeat until all the ingredients are used up, finish with the cream.
