preheat your oven to 425°f.
pierce the potatoes with a fork in several places and bake them for 45-60 minutes until they are tender.
let the potatoes cool down a bit, then peel them and mash them well in a large bowl.
add the flour and salt to the bowl and mix well until the dough forms.
knead the dough on a lightly floured surface until it is smooth.
divide the dough into 4 portions, and roll each portion into a long rope shape.
cut each rope into small pieces (around 1 inch each), and press each piece with a fork to make ridges.
fill a large pot with water and bring it to a boil.
add the gnocchi to the boiling water, and cook until they float to the surface of the water.
use a slotted spoon or strainer to remove the cooked gnocchi from the pot.
