Serves 4 to 6
2 cups (300 grams) “00” or all-purpose flour
2 large eggs
3 egg yolks, plus more as needed
Semolina flour, for dusting
Mound the flour in the center of a large, wide mixing bowl. Dig a well in the center of the mound and add eggs and yolks. Using a fork, beat together the eggs and begin to incorporate the flour, starting with the inner rim of the well. The dough will start to come together in a shaggy mass when about half of the flour is incorporated.
Use your fingers to continue to mix the dough. Press any loose bits of flour into the mass of dough. If needed, add another egg yolk or a tablespoon of water to absorb all of the flour. Once the dough comes together into a cohesive mass, remove it from the bowl.
Transfer to a lightly floured surface and knead by hand for 4 to 5 more minutes until the dough is smooth, elastic and uniform in color. Wrap the dough in plastic and set aside for at least 30 minutes (and up to 4 hours) at room temperature.
Line three baking sheets with parchment paper and lightly dust with semolina flour. Set aside.
Cut off a quarter of the dough. Rewrap rest, and set aside. Use the heel of your hand to flatten the dough into an oval approximately the same width as your pasta machine, about six inches. Set the rollers to their widest setting and pass the dough through.
Lay the dough out onto a lightly floured cutting board or countertop and neatly press together into halves, so it’s again about the same width of the pasta machine. Feed the pasta through again at the widest setting. Think of these first rollings as an extended kneading. Continue to fold the dough in thirds and roll it until it is smooth, silky and even-textured. Do your best to make the sheet the full width of the machine.
Once the dough is silky and smooth, you can begin to roll it out more thinly. Roll it once through each of the next two or three settings, adding flour as needed, until the dough is about 1/4-inch thick.
Once the pasta is about 1/4-inch thick, begin rolling it twice through each setting. As you roll, lightly sprinkle all-purpose or 00 flour on both sides of the pasta to prevent it from sticking to itself.
Roll out pasta until you can just see the outline of your hand when you hold it under a sheet, about 1/16-inch thick for noodles.
Cut pasta into sheets, about 12 to 14 inches long. Dust the sheets lightly with semolina flour and stack on one of the prepared baking sheets and cover with a clean, lightly dampened kitchen towel. Repeat with remaining dough.
To cut noodles with a pasta roller, run the pasta sheets, one at a time, through the cutting attachment, then toss with semolina flour. Gently fluff and separate noodles and pile into nests of single portions (about 3 ounces). Place on baking sheets lined with parchment paper and dusted with semolina, and cover until ready to use.
To hand-cut noodles, stack four sheets of pasta lightly dusted with semolina flour, then loosely roll into thirds lengthwise (like folding a letter). Cut with a sharp knife (in ½-inch increments for tagliatelle or fettuccine and into ¾-inch increments for pappardelle), continuing until all the dough is used. Gently fluff and separate noodles and pile onto prepared baking sheets into nests of single portions (about 3 ounces).
Cover until ready to use.
