For the dough, sift the flour, add a pinch of salt, 100 g of sugar and butter (chopped). Rub with your fingers until crumbs are obtained.
After crumb formation, add 1 egg and 2 tablespoons of warm (but not hot!) Boiled water. Mix until smooth. If the dough is very thin, add a little flour.
Wrap the dough in plastic wrap and leave in the refrigerator for about 30 minutes.
For the filling, grind 100 g of sugar with cottage cheese. Add starch, vanilla sugar, salt, cream, the remaining 4 eggs, mascarpone.
Immerse all the ingredients for the filling in a blender and beat until a creamy homogeneous mass is obtained.
Evenly spread the dough into a round, greased form with butter, form small sides (about 2-3 cm). Pour the whipped filling evenly on top of the dough.
Place the cheesecake in the oven for 45-60 minutes.
Let the cake cool and decorate it. You can use chocolate, fruit, jelly, nuts, etc. All options go well with the delicate and unpleasant taste of this wonderful cheesecake.
