Prepare the Dough: In a large mixing bowl, combine the farmer’s cheese, egg, flour, salt, and sugar (if using). Mix gently until the ingredients are just combined into a soft dough. Avoid overmixing.
Shape the Dumplings: Lightly flour a work surface. Roll the dough into a log about 1 inch in diameter. Cut into small, bite-sized pieces (about 1-inch long).
Boil the Dumplings: Bring a large pot of salted water to a gentle boil. Drop in the dumplings, stirring occasionally to prevent sticking. Cook until they float to the surface (about 2-3 minutes).
Drain and Serve: Remove the dumplings with a slotted spoon and drain. Toss them with melted butter to prevent sticking.
Add Toppings: Serve warm with buttery toasted breadcrumbs, sour cream, or a light sprinkle of sugar for a sweet twist.
