👨🍳 Instructions
- 1
Prepare the crust: In a food processor, pulse flour, sugar, and butter until coarse crumbs form. Add egg yolk and ice water, pulsing until dough just comes together. Do not overmix.
💡 Tip: Keep ingredients cold for a flaky crust. - 2
Shape the dough into a disc, wrap in plastic wrap, and refrigerate for at least 30 minutes.
- 3
Preheat oven to 180°C (350°F). Roll out the dough and line a 23cm (9-inch) tart pan. Prick the bottom with a fork and blind bake for 15 minutes with pie weights or dried beans.

Prepare the filling: In a bowl, whisk together kohupiim, sugar, eggs, vanilla extract, lemon zest, and cornstarch until smooth and well combined.
- 5
Remove the partially baked crust from the oven. Pour the kohupiim filling into the crust. If using berries, scatter them over the filling.
- 6
Bake for 25-30 minutes, or until the filling is set and lightly golden. The center should be just slightly jiggly.
- 7
Let the tart cool completely in the pan before slicing and serving. This allows the filling to fully set.
💡 Pro Tips
- ✓If you can't find kohupiim, a good quality farmer's cheese or ricotta mixed with a little Greek yogurt can be a substitute.
- ✓Ensure the filling is smooth to avoid lumps.
- ✓Serve chilled or at room temperature. Dust with powdered sugar if desired.
🔄 Variations
- Add a layer of thinly sliced apples or pears to the bottom of the tart before adding the filling.
- Incorporate a tablespoon of rum or brandy into the filling for an adult twist.
- Use a different fruit, such as cherries or apricots, instead of berries.
