Using a fork, lightly beat the eggs until they are completely broken up.
Working from the inside of the mound, start to incorporate flour into the eggs, taking a little at a time, maintaining the "walls" of the mound for as long as possible.
3. Once all of the flour has been incorporated into the eggs, the mixture will be very rough and shaggy.
Begin working the mixture with your hands and knead the dough, just as you would bread dough, until the dough is smooth and elastic, which can take up to 10 minutes.
4. Cover the dough with a piece of plastic wrap and allow to rest for at least 15 minutes, or up to 2 hours.
5. If you are making the dough for filled pasta (like ravioli or tortellini) or lasagna, cut the dough into four equal pieces (shown here). If you are making the dough for noodles, cut the dough into eight equal pieces.
6. Work with one piece of dough at a time (keep the others covered with plastic wrap so they do not dry out). Flatten the dough into an oblong shape and pass through the pasta machine on the widest setting (usually 1).
7. Dust the dough lightly with flour, then fold the dough into thirds.
Pass through the pasta machine's widest setting again, feeding the open side of the dough through first. Pass the dough through again once more, for a total of three times.
8. Lightly flour the dough if it is sticky, and adjust the setting to the next level (number 2), and pass the dough through two times.
9. Continue to roll the pasta thinner by passing it through the machine repeatedly, using a narrower setting for each pass going forward. If you are making filled pasta (ravioli or tortellini), you should end on the thinnest setting. For lasagna or noodles, end on the next-to-thinnest setting.
10. Lay the sheets of pasta on a clean dish towel dusted lightly with flour. If you will be using the sheets for lasagna or filled pasta immediately, cover the pasta with another damp dish towel to keep from drying out. If you will be cutting the pasta into noodles, do not cover and allow to sit until only slightly tacky, 10 to 15 minutes. At this point, you can use a fettuccine or spaghetti attachment on the pasta machine and run each sheet through, creating noodles. If you prefer wide noodles, you can cut pappardelle (¾ to 1 inch wide) and tagliatelle (¼ to ⅜ inch wide).
11. Immediately transfer the noodles to a baking sheet lined with a clean dish towel, separating individual strands as best you can. If planning to cook immediately, cover the noodles with a damp dish towel so that they do not dry out. If you would like to store the pasta for future use, gather several strands as you cut the pasta and curl them into nests. Allow them to dry on the clean, flour-dusted kitchen towel for 24 hours. After they are completely dry, they can be stacked in an airtight container for up to 2 weeks. Filled pasta, such as ravioli and tortellini, can be placed in a single layer on a baking sheet to freeze. Once completely frozen, they should be transferred to a resealable freezer bag and can be kept in the freezer for up to 1 month.
