Pierogi leniwe (lazy cottage cheese dumplings)

Instructions

1. Drain the cottage cheese for an hour in a sieve lined with kitchen paper to remove excess water.
2. In a bowl, mix the cottage cheese, egg, sugar, salt and vanilla until you have a smooth mass.
3. Gradually work in the flour to form a soft dough that no longer sticks. Add more flour only if it is too sticky.
4. Divide the dough into 4 logs and roll them on a floured surface into ropes about 2 cm thick.
5. Cut the ropes into pieces about 2 cm long and drop them into a large pan of simmering salted water for 3 to 4 minutes, until they float to the surface.
6. Drain them, then fry for 2 minutes in melted butter. Sprinkle with breadcrumbs and sugar, and serve with the crème fraîche.
