Cook the potatoes in the jacket until they are soft (approx. 45 minutes - depending on size). Let them cool down a little before peeling them. If you can, let them cool down for several hours or overnight.
Press the cooked potatoes through a potato press or mash them as fine as possible with a potato masher.
Add the remaining ingredients and stir until it forms a fluffy dough that is easily shaped. If needed, add water by the tablespoon until the texture is right.
Form the dumplings into the shape seen on the photos and place them on a surface dusted with flour. In the meantime bring a large pot of water to the boil.
When the water is boiling, place the dumplings in the pot. Cover the pot with a lid and turn off the heat. The finished Schupfnudeln will swim on the surface.
Scoop the cooked dumplings out of the water and place them directly in a lightly greased frying pan. Fry them from both sides and serve. Enjoy :)
