Add 3 cups of the flour, eggs, and salt. Using a dough hook on your mixer, mix the dough for about 2 minutes or until the dough is really gooey and stringy, scraping down the sides of the bowl as needed.
Add flour only until the dough pulls away clean from the edge of the bowl, up to 1 more cup. It will ensure you don't add too much flour to your dough.
