Boil potatoes until tender, then peel and mash them.
In a bowl, combine the mashed potatoes, flour, and a pinch of salt.
Add the egg and mix until a dough forms.
Transfer the dough to a floured surface and knead gently.
Divide the dough into smaller portions for easier handling.
Roll each portion into a long rope, about 1/2 inch thick.
Cut the ropes into 1-inch pieces to form the gnocchi.
Use a fork to create ridges on each piece for better sauce adherence.
Bring a pot of salted water to a boil and add the gnocchi.
Cook until they float to the surface, then remove with a slotted spoon.
