For the filling, wash the currants and strip them from the panicles. Bring to the boil with the sugar and water. Mix the vanilla pudding powder in 3 tablespoons of water and add to the currants. Bring to the boil briefly and allow to cool.
Mix the flour, sugar, vanilla sugar, almonds and margarine into a dough. Let rest in the refrigerator for about 30 minutes. Press 2/3 of the dough into a greased springform pan (diameter 26 cm), pulling up a small edge. Spread the filling on top and spread the remaining dough on top in the form of sprinkles.
Bake at 180 ° C for 45-50 minutes until the crumble browns slightly.
