Whole-grain strudel with apples

First, preheat the oven to 185–190 °C, prepare a baking sheet (30 cm × 40 cm) and line it with baking paper.

In a large bowl, combine the flour, 1 egg, butter, and yogurt. Knead into a smooth, firm dough and let it rest aside at room temperature for at least 10 minutes.

Meanwhile, peel the apples, remove the cores, and coarsely grate them into a large bowl. Then add cinnamon, sugar, pudding powder, and raisins to the apples and mix everything together.
