Peel carrots and grate them finely with a kitchen grater. Then sauté with butter in a hot pan until almost done. Add the sugar and let it fry a little bit more in the pan. Season with a little salt and let it cool down.
Now mix (knead) ricotta, parmesan, flour, mashed potatoes, salt and pepper and season to taste. Add egg and egg yolk and mix well.
Form approx. 12 dumplings and cook in salted water (boiling) for approx. 10 minutes. Decorate with cress when serving. Green pesto and/or a steak go well with it.
