Sandwich an even layer of ricotta between 3 paper towels on a large plate and another 3 towels above, then press lightly to blot away whey. The towels should become damp as the cheese loses its wet sheen.
Stir the blotted ricotta, parmesan, eggs, flour, salt, pepper, and any chosen optional aromatics together in a large mixing bowl, stopping once combined. The finished mixture should hold together as a soft dough with a slightly sticky surface.
Start a large pot of salted water boiling while you move the dough onto a large, lightly floured cutting board, dust its surface, and divide it into four portions. Each portion should remain soft but lift from the board with gentle handling.
Shape each portion into a thick rope and slice across it to make bite-sized rectangular dumplings. The cut pieces should resemble small pillows, with enough surface flour to release from the board.
For the optional freeze-for-later route, arrange the uncooked pieces on a parchment-lined baking sheet, freeze until solid, and pack them into a large freezer bag. Wait until the pieces feel firm throughout before bagging so they retain their separate shapes.
Lower the dumplings carefully into boiling water, cook for roughly one minute after they rise to the surface, then drain and gently coat with your chosen sauce. Floating pieces should remain intact, with tender centers rather than a dense, floury interior.
