For the curd strudel, finely slice the apples and sprinkle with a little lemon juice. Rinse the beans well with cold water, put them in a bowl and mash them coarsely.
Add the apples to the beans, add a little cinnamon and stir well. If desired, you can also soak some raisins (water or rum).
Beat an egg with a pinch of salt, sugar and butter. Gradually add curd cheese, sour cream and semolina. Add the raisins. Stir the apple and bean mixture into the curd mixture.
Spread this filling on the rolled out puff pastry and roll into a strudel. Prick the strudel several times with a fork – this prevents the strudel from tearing open during baking.
Brush with beaten egg. Sprinkle with almond slivers. Bake the strudel in a preheated oven at 170 °C convection oven for approx. 20-30 minutes until a nice brownish color is achieved.
