01 - Boil the peeled and quartered potatoes in salted water until tender, about 15-20 minutes. Drain and let cool slightly.
02 - Mash the potatoes until smooth and allow to cool completely.
03 - In a large bowl, combine cooled mashed potatoes, flour, egg, and salt. Mix until a dough forms. Optionally, add potato starch for extra fluffiness.
04 - On a floured surface, divide the dough into smaller portions and roll each into a log about 1.5 cm thick. Cut into 2 cm pieces and press a small indentation in the center of each with your thumb.
05 - Bring a large pot of salted water to a boil. Cook the dumplings in batches until they float to the surface, about 3-4 minutes. Remove with a slotted spoon.
06 - Serve the dumplings immediately with your choice of sauce or toppings.
