Sieve the flour on a work surface and make a well in the middle. Add the eggs, yolks, oil, salt and the chopped mixed herbs. Process everything into a smooth dough, adding a little water (if necessary). Let the dough rest in the refrigerator for 1 hour, wrapped in foil.
Finely chop the onions and garlic. Carefully clean the boletus and cut into 5 mm cubes. Melt the butter and sweat the onion and garlic cubes in it until translucent. Sweat the porcini mushrooms for 3–4 minutes. Sprinkle with salt, pepper and parsley. Let cool down completely.
For the sauce, peel the shallots and chop them very finely. Melt the butter in a saucepan and sweat the shallot cubes lightly. Deglaze with white wine and reduce to about 1 tablespoon. Pour in the cream and reduce to half. Salt, pepper and sprinkle in the chives rolls.
Roll out the pasta dough evenly thinly on a work surface and rub out rectangles of 6 x 11 cm from the dough. Put 1 teaspoon of filling on each piece of dough and brush the edges with egg white. Fold the pieces of dough lengthways on top of each other and press down the edges well. Place the dumplings in boiling salted water and cook for about 8 minutes. Take out, drain and serve with the chive sauce.
The Boss Kitchen editorial staff oversees content review, fact-checking, and recipe verification across the site. Published articles pass through the editorial team before going live, ensuring ingredient lists, techniques, cooking times, and nutritional claims hold up in a home kitchen. The team coordinates contributions across the site writers, handles reader corrections, and maintains consistency in measurement conventions, safety guidance, and dietary labeling. Posts under this byline typically represent team-reviewed reference material, site announcements, or editorial roundups rather than individual-author features, and they are held to the same sourcing standards as bylined recipe and product coverage.
