Dough: in a bowl, combine the flour, a pinch of salt, sugar, baking powder and sesame seeds. Stir.
Add the cold butter and sour cream.
Start mixing with your hands, kneading the dough and collecting it into a ball. The dough is soft, smooth, not sticky to the hands.
In a baking dish, put the dough (diameter 20 cm, the bottom is covered with parchment), distribute the form with your hands, forming the bottom and high sides, prick the dough with a fork. Put it in the refrigerator while cooking the curd filling.
Curd filling: combine the curd and persimmon slices in a bowl. Mix thoroughly with a blender until smooth.
Add eggs, sugar, sour cream, and cornstarch.
Once again, mix thoroughly with a blender until smooth.
Put the curd filling in the prepared form with the dough. Send it to bake in a preheated 190 degree oven for 55-60 minutes (we focus on the features of our oven and the Golden top of the curd).
Let the finished curd cool completely, then put it in the refrigerator for 3-4 hours, or better-overnight.
