2 cups "00" flour
1 1/4 cups large egg yolks (about 16 yolks)
Mound flour in center of a large work surface and make a well in the middle. Place egg yolks and 1 tablespoon water in well.
Using a fork, slowly incorporate flour, beginning with inner rim of well. When flour is incorporated, gather dough together to form a rounded mass. Begin kneading dough with the palms of your hands; knead dough until smooth and elastic. Cover with plastic wrap and let stand 20 minutes before using.
