Let the dough sheets rest at room temperature for about 10 minutes. Remove 4 sheets, wrap the remaining filo pastry sheets in foil, store in the refrigerator and process in a timely manner.
Roast the flaked almonds in a pan without fat, remove. Wash apples, remove seeds and cut into 8 slices. Caramelise the sugar in a pan, deglaze with lemon juice. Let the apple slices and raisins steep in the caramel for about 4 minutes while turning.
Cool down on a kitchen roll and drain.
Drain butter in a pot. Cut filo pastry sheets in half, press them together roughly and place the "pastry fans" on 2 baking trays. Brush the dough with liquid butter and bake in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see
manufacturer) bake for about 5 minutes until golden brown, remove from the oven and allow to cool.
Arrange 2 pastry fans and 2 apple slices in layers on plates with a ball of vanilla ice cream. Decorate with raisins and flaked almonds. Dust the strudel towers with icing sugar.
