Add the flour to a clean work surface. Create a well in the middle and add the eggs, egg yolks, and salt into the center. Using a fork, whisk the eggs together, pulling in small amounts of flour as you go. Continue this process until a thick egg paste forms. Then pull in more flour, combining more and more as you go. Once you can no longer combine using the fork, switch to your hands and slowly knead the dough together. Add water, one teaspoon at a time, as needed to help the dough form and bind together. You might not use all of the water.
2 cup 00 flour, 2 large egg + 2 egg yolk, ¼ teaspoon salt, 1-5 teaspoon water
Once all of the flour is incorporated into the dough, knead the dough, using the heel of your hand, for five to ten minutes, or until the surface is smooth and elastic. Dough should pop back when poked, and no crumbs or lumps should be visible.
Wrap the dough in plastic wrap and leave it at room temperature to rest for at least one hour and up to three hours. The dough should spring back slowly when pressed with your finger after it is fully rested. The dough can also be refrigerated for one day or frozen for up to a month. If chilling, let the dough return to room temperature before continuing to the next step.
Add ½ cup of dusting flour to a large, shallow bowl.
Unwrap the dough and divide it into four equal portions. Working with one portion at a time, press the dough piece into a rough rectangle. Cover the remaining portions with plastic wrap or a damp towel so they do not dry out.
Fit a stand mixer with the pasta roller attachment or secure a hand-cranked pasta maker. Set it to “0”, or the widest setting. With the stand mixer on the slowest setting, or cranking very slow, pass the shortest end of the dough through the roller twice.
Transfer the pasta to a clean work surface and fold one of the short ends of the dough into the center. Do the same with the other side, completing a letter fold.
Pass the dough through the widest setting again, leading with the shortest side of the dough. The goal is a smooth rectangle with no scraggly edges. Repeat this process until the dough is a perfect, smooth rectangle.
Adjust the dial of the pasta attachment to the next, smaller setting and pass the dough through twice. Repeat this process until the dough is 1/8th inch (3.2 milimeter) thick, or on the number six setting. If the rectangle becomes uneven, fold the dough to form smooth edges, go back a setting, and pass through twice before returning to the next smaller setting. Dunk pasta sheets in the flour bowl, to lightly cover all sides.
Line two sheet trays with parchment and rice flour or semolina. Add the pasta to one of the sheet trays, adding additional flour and folding the dough over to fit the sheet tray. Completely dusting the dough sheets prevents the dough from sticking together.
½ cup rice flour or semolina
Cover dough sheets with a towel or plastic wrap.
Repeat the dough rolling process with the additional dough balls.
Cut the pasta sheets to fit the length of a chitarra. Add each dough sheet to the chitarra, then using a small rolling pin, gently roll across the surface to cut the pasta into strips.
Toss spaghetti in the bowl with flour to coat and transfer to a pre-lined sheet tray, and repeat until all of the pasta is cut. Cover pasta with a towel or plastic wrap until ready to cook.
