An analogue of cottage cheese donuts, it's just a matter of slicing
Curd needs to be smooth. If you have grainy - dare in a blender. Pour in the egg, sour cream, add sugar, salt, soda, flour and mix everything well. More flour may be required, it all depends on the cottage cheese. I lost 1 glass. Knead a soft dough.
Sprinkle the work surface with flour. Roll out a layer 2-3 cm thick from the resulting curd mass. Cut into sticks of any length convenient for you.
Deep fry on all sides until golden brown. Immediately fold the finished sticks on paper towels and sprinkle hot with plenty of powdered sugar.
