Whisk fat, 100 g sugar, vanillin sugar and salt with the whisk of the hand mixer until white-creamy. Separate the eggs and chill the egg white. Add egg yolk to the fat-sugar-mixture and stir until thick and creamy. Mix flour and baking powder. Stir in half, knead in the remaining flour with the dough hooks. Chill the dough for 20-30 minutes.
In the meantime wash the currants, drain GUT and put some aside for decoration. Strip remaining berries from the panicles. Roll out the dough to a circle (approx. 35 cm Ø) on a floured work surface. Line a greased springform pan (26 cm Ø) with the dough and press down firmly at the edge (the edge of the springform pan should be 4-4.5 cm high). Prick the base several times with a fork and sprinkle breadcrumbs on top if necessary. Refrigerate the mould for another 10 minutes. Carefully mix/swivel currants and starch. Beat the egg whites until stiff, gradually add 200 g sugar and continue beating for 4-5 minutes. Fold 2-3 portions of egg white into the currants. Pour into the tin, smooth out loosely and bake in a preheated oven, lowest shelf (electric oven: 175 °C/ gas: level 2) for approx. 50 minutes. In the meantime, beat 1 egg white until stiff, finally add 60 g sugar and fold in lemon juice.

Put back into the oven and bake in about 20 minutes. Remove the cake from the oven and let it cool on a grid in the mould. Carefully remove the lukewarm cake from the edge with a knife. Remove the cooled cake from the tin, decorate with the remaining currant panicles and dust with icing sugar
