Preheat the oven to 180 °C. Put the flour in a bowl, add flakes of butter and sprinkle the cane sugar on top. Work the mixture with your hands to form a crumble. Wash the apples and cut them into slices using the bamix® SliceSy® with disc no. 4. Scrape out the pulp from the vanilla pod and add to the sugar; mix in. Wash the bilberries and mix them in, as well. Place the fruit mixture in heat-resistant ramekins and cover generously with the crumble.
