Instructions

Working time approx. 30 minutes; Rest time approx. 1 hour 30 minutes; Cooking/baking time approx. 50 minutes; Total time approx. 2 hours 50 minutes

For a 26cm springform pan. Also available vegan.

First make the crumble, as it needs to sit for a little longer so that the oats can absorb the moisture properly. To do this, mix the flour, oats, sugar, cinnamon, and salt. Then knead it with the butter to form a dough. Wrap this in cling film and place in the refrigerator for about 1 hour. For the shortcrust pastry, mix the flour, sugar, orange zest, and salt. Add the egg and butter and knead until a smooth dough forms. Then wrap the dough in cling film and place in the refrigerator for about 30-60 minutes. For the topping, finely dice the onions and sauté them with half of the red wine in a hot small pan or small hot saucepan over medium heat until the red wine has evaporated. Then add the remaining red wine and continue sautéing until the red wine has evaporated. Set the onions aside and let it cool. Now halve the plums and remove the stones. Roll out the dough on a lightly floured work surface/mat and place it in a greased 26 cm springform pan. This should create a 2-3 cm high edge. Now arrange the plums on the base. This works best when standing on their long sides. Then distribute the red wine onions evenly over the plums. Finally, crumble the crumble mixture over the cake. Preheat the oven to 200°C (top/bottom heat). Bake the cake for about 40 minutes. Once the cake is completely cool, remove it from the pan. Vegan version: Replace the butter with vegan butter or margarine and the egg with two tablespoons of ground flaxseed and three tablespoons of water. Tip: If the plums are very ripe and slightly soft, the cake will be particularly tasty.
