The preparation for the dough
Slice the vanilla pod lengthwise, scrape out the seeds with a knife, mix it with the sugar, and rub the seeds apart until there are no clumps left.
Add the sugar to the flour, mix in the butter and salt, and then the beaten egg yolk.
Roll into a ball and let it firm up in the refrigerator for an hour. Meanwhile, make the cheese filling.
The preparation for the filling
Mix the cream cheese and cottage cheese with the cream.
Then add the brown sugar, flour, lime and orange zest, the juice of one lemon, and the beaten eggs one by one.
For the finishing
Preheat the oven to 200 °C.
Roll out the dough for the base on a floured surface. Shape it to fit the springform: round or square. Grease the form, dust it with some flour, tap out the excess, cover the bottom with the sheet of dough (only covering the bottom and not the sides) and bake for 10 to 12 minutes. Let it cool slightly.
Turn the oven up to 275 °C.
Pour the cheese filling into the form.
Bake first for 12 minutes at 250 °C and then for another hour at 100 °C.
Let cool and refrigerate for at least 4 hours. Cheesecake is best served chilled.
Just before serving, cover the top with a thick layer of unsweetened cottage cheese that you pipe on in dollops with the piping bag. You can also finish the cheesecake very casually by spreading the cheese on the cake with a knife.
