Instructions
Make the short‑crust dough
In a large mixing bowl combine 200 g flour, 30 g potato starch, 50 g sugar, and a pinch of salt. Add 100 g softened butter cut into small dice and mix until the mixture resembles coarse sand. Stir in 5 ml apple cider vinegar, 30 ml cold water and one egg yolk, then mix with a hand mixer or by hand until a smooth, creamy dough forms.
Time: PT15M
Chill the dough
Shape the dough into a ball, wrap tightly in plastic wrap and refrigerate for at least 1 hour to firm up.
Time: PT1H
Pre‑bake the crust
Preheat the oven to 180 °C (fan‑forced). Butter a 20 cm square pan, line with parchment paper, and press the chilled dough evenly into the base. Smooth the surface with a spatula. Bake for 15 minutes until lightly golden.
Time: PT15M
Temperature: 180°C
Prepare the caramelized apples
Peel, core and cut the apples into 2 cm cubes. In a large sauté pan melt 30 g butter, add 50 g sugar and stir until it begins to foam. Add the apple cubes, sprinkle the seeds of one vanilla bean, and cook over medium heat for about 15 minutes, stirring occasionally, until the apples are tender and golden.
Time: PT25M
Cool the base and apples
Remove the pre‑baked crust from the oven and let it cool on a rack for 10 minutes. Allow the caramelized apples to cool slightly as well, then spread them evenly over the crust, pressing gently to create a flat surface.
Time: PT10M
Bake with the apples
Return the pan to the oven and bake for 30 minutes at 180 °C until the apples are set and the edges of the crust are golden.
Time: PT30M
Temperature: 180°C
Prepare the almond crumble topping
In a bowl combine 80 g flour, 80 g almond powder, 80 g brown sugar and 5 g ground cinnamon. Add the cold 80 g butter diced and rub it into the dry ingredients with fingertips until the mixture resembles coarse crumbs. Do not over‑work.
Time: PT10M
Chill the crumble
Place the crumble mixture in the refrigerator for about 10 minutes so it stays cold while the second bake begins.
Time: PT10M
Add crumble and final bake
Scatter the cold crumble evenly over the baked apples. Return the pan to the oven and bake for 20 minutes at 180 °C, or until the crumble is golden brown and crisp.
Time: PT20M
Temperature: 180°C
Cool, demould and serve
Allow the finished crumble to cool completely at room temperature (about 30 minutes). Gently remove the parchment paper and cut the square into nine even pieces. Serve warm or at room temperature.
Time: PT30M
