Prepare the plums, cut each one into 3-4 pieces. Add 3 tbsp sugar and let it rest to release the juices and soften a little.
Use all the ingredients to make the dough. Let it chill in the fridge for at least half an hour.
When your dough is ready, take approximately 60% of it for the lower pie crust. This dough is too buttery and flaky so it’s not possible to roll it and transfer into the pie dish. So just use your hands and spread it in the pan directly. Sprinkle with a little cornstarch.
Drain the plums, add 3 tbsp sugar, 2 tsp cornstarch, lemon juice, cinnamon and vanilla. Combine well and and arrange them onto the crust. Now take the remaining dough and flake it on top by using your hands.
Mix one egg yolk with milk and coat the surface of the pie. Sprinkle with some brown sugar.
Bake on 190 deg C for 30 min, and another 15 min od 170 deg C.
Serve with vanilla ice cream!!!
