Add the flour to a large bowl. Make a well in the center; add the eggs and yolk.
Whisk together with a fork, and then combine with the flour. When the texture becomes stiff, finish by hand to form a rough dough.
Form the dough into a ball, cover with an upturned bowl or with plastic wrap, and let rest at room temperature for 10-15 minutes.
Knead the dough for 5-7 minutes until soft and malleable.
Cover tightly with plastic wrap, and rest at room temperature for 30 minutes.
Cut the pasta dough into 4 pieces. Flatten one piece into a 6-8 inch oval patty.
Set the pasta roller to #1 and send the dough through the roller twice.
Continue to roll the dough through settings #2-4, (2x) on each setting.
Dust the pasta sheet generously with semolina, fold it in half, and place onto a floured sheet pan.
Hang the pasta sheets over the back of a chair for about 10-15 minutes.
Cut the pasta sheet in half and run it through your desired pasta cutter attachment.
