First, soak the lentils for one night.
The next day, drain them. Finely dice the onion and carrots and sauté in a little butter. Add lentils, saute for 2 to 3 minutes at low temperature, stirring well. Pour in water, bring to a boil, simmer gently at low temperature for 20 to 25 minutes.
For the dumplings, cut the rolls into cubes. Finely chop the onion and parsley, fry in butter. Mix with flour in a large bowl, add salt, pepper and nutmeg (freshly grated). Add onion-parsley mixture. Mix the two eggs in milk, let stand for 10 minutes.
Form a sausage from the mixture, wrap in plastic wrap and seal tightly. Cook in boiling water for about 25 minutes.
Make croutons according to this recipe.
Season lentils with cumin, salt and pepper only at the end. Continue cooking for 5 to 7 minutes. Then mix in crème fraîche.
Sprinkle the lentils with napkin dumplings with finely chopped chives and the croutons.
