Press the warm potatoes through a potato press (if you have one) or mash them with a potato masher into a bowl. NEVER use a food processor since the consistence of the potato mash will be ruined for the dish.
Add salt, egg yolks, maizena, cake flour and nutmeg and mix everything quickly together. You don't want to overmix the dough but need the ingredients to be well combined.
Put the dough onto a floured surface and divide it into 2 pieces.
Roll the first piece into a log. The diameter should be approimately 3 cm.
Cut the dough log into 2 cm pieces .
Use your hands to roll each piece into a finger-shaped dumpling with thick middle and tapered ends. Dust them with a little flour.
In a large pot bring water to a boil and cook the potato dumplings in batches.
Once they float, they are ready.
Take them out of the water and let them dry in a single layer for about 10 minutes.
Heat the butter in a non-stick pan and fry the potato dumplings until browned all over(tr aditional way)
If you don't want to fry them in butter, you could place the Schupfnudeln onto a lined baking tray and bake them for 15 to 20 minutes in a preheated oven at 200 degrees C.
You can serve them with homemade red cabbage and a roast or goulash.
