Separate eggs. Beat egg whites until stiff. Let sugar trickle in. Stir in egg yolk. Sift the flour and starch over it and fold in carefully. Line the bottom of a springform pan (22 cm Ø) with baking paper.
Pour in the dough and bake in the preheated oven (electric: 200 °C/ gas: level 3) for approx. 20 minutes. Remove from the oven, remove from the mould and allow to cool. Soak gelatine in cold water. Whip cream and vanillin sugar until stiff.
Stir in the pistachios. Squeeze the gelatine, dissolve over a mild heat and stir into the cream. Place the cake ring around the base. Spread the cream on top and refrigerate. Sort the berries. Wash and stone the cherries.
Add all the fruit to the cream. Mix the cake glaze powder, sugar and currant juice in a pot, bring to the boil and immediately spread over the fruit. Refrigerate again. Carefully loosen the cake ring.
