For dumplings, it is best to take dry crumbly cottage cheese, ideally homemade. If you buy cottage cheese in a store, squeeze it well before cooking.
Mix cottage cheese, flour and eggs. Roll out the mass in the form of sausages and cut into pieces with a knife.
Boil in salted water until all dumplings float to the top. Throw on a sieve, let the water drain, put in a wide form or pan, pour over with fresh sour cream and bake.
