Wash the currants, drain and remove from the panicles. Beat the fat, salt, vanillin sugar and 100 g sugar with the whisk of the hand mixer until foamy. Stir in the eggs one after the other. Mix flour, baking powder and starch, add and stir in. Pour the dough into a greased springform pan (26 cm Ø) sprinkled with flour, smooth it down. Spread currants evenly on top.
Bake in the preheated oven (electric range: 200 °C/ convection oven: 175 °C/ gas: level 3) on the middle shelf for about 15 minutes. In the meantime, beat the egg whites until stiff, pour in 100 g sugar and continue beating until the sugar has dissolved. Fold in the grated coconut. Take the cake out of the oven, carefully spread the coconut mixture loosely on top and bake at the same temperature on the lower rack for 35-40 minutes. Remove from the oven, immediately remove from the edge of the springform pan and allow to cool in the pan. Remove from the mould, dust with icing sugar and decorate with currants.
