Combine flour and salt in a large bowl. Add ½ cup water and use a spoon to stir to combine. Add more water if needed to create a shaggy dough ball. Use your hand to start kneading the dough. Sticky? Add a bit of flour. Too dry? Add a bit of water.
Knead the dough until the dough ball is shiny, and not at all sticky.
Set aside, covered, for 15 to 30 minutes.
Flour a surface (you can use the bottom of a baking sheet if you don’t have a good surface) and roll out the dough ball until very thin.
Flour the top of the dough, then fold it up on itself over and over. Slice the roll ¼ inch thick to create long strands of pasta. Pick up the pasta and shake off the excess flour.
Cook in boiling water for 2 to 3 minutes.
