preparation
Knead the flour, baking powder, eggs, margarine, sugar and vanilla sugar to form a smooth dough. Set aside for around ½ hour. Peel the apples for the filling, cut into small pieces and mix with the sugar, vanilla sugar and sultanas. Add rum to taste. Finally, cut the dough into 2 pieces, roll out and add filling. Then brush the strudel with cold milk. Bake in oven at 180 °C for around 45 minutes. Sprinkle the still-warm strudel with icing sugar and serve with custard, if desired.
