All ingredients ready? Let's begin!
In a large mixing bowl, add the flour and salt. Stir to combine. Add the water and use your hands to mix everything until the dough starts to come together.
Continue using your hands to knead the dough until all the flour is incorporated into the dough. If necessary, add a little more water to the dough to bring everything together.
Lightly dust a clean, dry, flat work surface with flour. Turn the dough out onto the floured surface and continue to knead with the heels of your hands until it is elastic and smooth, approximately 5 minutes.
Wrap the ball of dough in plastic film and allow it to rest at room temperature for at least 1 hour and up to 4 hours.
After the dough has rested, flour your work surface again lightly. Knead the dough for about 2 or 3 minutes. Form the dough into 3 equal size balls. Dust the balls with flour and wrap 2 of them in the plastic while you work on the first one.
Lightly dust your work surface again. Using a rolling pin that has also been dusted with flour, start rolling out one ball of dough, rotating it 90 degrees every so often. Add a little more flour if the dough starts to stick to the surface or the rolling pin. You want the dough to be between 1/8 and 1/4 inch thick, but not any thicker.
Fold the rolled-out dough into thirds, overlapping the folds. It will resemble a folded letter.
Using a sharp chef’s knife and starting at one of the shorter ends, slice the dough into 1/8-inch wide noodles. After they are sliced, gently separate the noodles using floured hands so they don’t clump together, and place them in a pile on a sheet pan or your work surface. Repeat with the other 2 balls of dough.
You will want to cook the noodles right away. To do that, bring a large pot of salted water over high heat to boil. Have ready a large bowl of ice-cold water and a colander. Add noodles to boiling water and cook them for approximately 10 minutes while stirring and checking a couple of times for doneness.
Drain the noodles in the colander and then place them directly into the ice-cold water bath for just 15 seconds to remove the excess starch and stop the cooking. Drain again and use the noodles in soups or stir fry dishes.
