TO MAKE THE PASTA, place the flour in a mound on a smooth work area, creating a well in the center. Pour the 2 beaten eggs and 2 egg yolks into the well, and slowly pull the flour into the eggs until it is all incorporated. Finish kneading by hand, adding more flour if needed for a smooth consistency. Divide the pasta in half and roll out each half or feed through pasta roller until thin, number 6 setting on the machine. Roll out as many sheets of pasta as possible.
