Rub the bowl (or a baking dish) with butter and sprinkle with the coconut flakes. Cover with the ladyfingers and drizzle with pineapple juice (possibly also with alcohol, amaretto, etc.)
Whip the cream until stiff. For the cream, mix the mascarpone with the sweet and sour cream until it is nice and creamy. Mix in the vanilla sugar, sugar, the pineapple cut into pieces (as much as you like) and the chopped almonds.
Put the cream on the ladyfingers and decorate with almonds and pineapple pieces. Overnight in the refrigerator.
