Mix flour, eggs, egg yolk, 1 teaspoon of salt, nutmeg and mineral water to a smooth, thick dough. Let dough rest for about 1 hour. Wash and clean the chanterelles. Wash the meat and pat dry. Cut the bacon slices in half lengthwise. Put 1/2 slice around each medallion and fix with wooden skewers.
Boil up plenty of salted water. Put some spaetzle dough on a spaetzle slicer and slice the spaetzle into the boiling water. Bring to the boil until the spaetzle rise. Lift out the spaetzle with a skimmer, put it in a sieve and rinse briefly with cold water. Drain and keep warm. Process the rest of the dough in the same way. Heat the oil in a pan.

Fry the chanterelles in the frying fat while turning, deglaze with wine and 1/4 litre of water, bring to the boil, season with salt and pepper and thicken with sauce thickener. Bring to the boil again. Melt butter in a pan, toss spaetzle in it. Arrange spaetzle, medallions and mushroom sauce on a plate.
