Knead the flour, margarine, icing sugar, 70 g grated almonds, 1 egg and vanilla sugar to a dough and leave to rest in a cool place for 2 hours.
Then roll out the dough thinly on a baking sheet lined with baking paper and bake at 180 degrees for about 15 minutes. Mix the strawberry jam with the rum and spread on the pre-baked dough. Beat the egg white into very firm snow, stir in icing sugar and fold in 100 g of grated almonds. Spread this mixture on the jam on the dough and bake for about 20 minutes at 180 degrees, let cool and cut into small rectangles.
