Method
- In a large mixing bowl, combine the flour (reserve 3 tablespoons), sugar, vanilla sugar, salt, lemon zest, cinnamon, and baking powder.
- Whisk the egg with 2 tablespoons of water, then pour it into the dry ingredients along with the butter pieces.
- Mix until the dough breaks into small, crumbly pieces—about pea to walnut size.
- Dust the reserved tablespoon of flour over the crumbs and toss gently, avoiding overworking it.
- Butter a deep 30x40 cm baking sheet and dust the bottom lightly with the remaining 2 tablespoons of flour.
- Scatter the crumble mixture evenly, then press it into the pan and build a slight edge around the border.
- Chill in the fridge for 30 minutes.
- Preheat the oven to 200°C (390°F) for top/bottom heat, or 180°C (350°F) for convection.
- Bake the base for 20–25 minutes until golden and dry to the touch, then let it cool completely.
- Split the vanilla pods lengthwise and scrape out the seeds. Combine the cream, milk, vanilla seeds, and pods in a saucepan and warm over medium heat until it just starts to steam.
- Let it steep for 5 minutes, then whisk the eggs, yolks, sugar, mascarpone, quark, vanilla liqueur (if using), cornstarch, lemon zest, and juice in a large bowl until smooth.
- Strain the warm vanilla cream into the egg mixture while whisking constantly, then pour the custard over the cooled base.
- Bake at 160°C (320°F) for 45–55 minutes until the center jiggles slightly but the edges are set.
- Once cooled, sprinkle the top with coarse brown sugar and caramelize using a kitchen torch.
- Let the sugar harden for 5 minutes before slicing into squares with a hot knife.

Notes
Make sure to use fresh ingredients for the best flavor. Store the base and custard for up to 2 days before caramelizing the top. Try variations like adding pureed berries for a fruity twist. Don't skip the pre-baking step; it's essential for a crispy base. Caramelize just before serving to maintain the crust's texture.
