Dump the flour into a large bowl or onto a clean work surface. Use your fingers to create a well in the center of the flour. In a separate bowl, whisk the egg and egg yolks just to combine.
Using a fork, start whisking the eggs, gradually incorporating the flour bit-by-bit. Continue to whisk, pulling more and more flour into the eggs, until a soft, shaggy dough begins to form.
Dump the whole shaggy mess out onto a clean work surface and use your hands to begin to knead it. To knead, fold the dough over onto itself, press it down with your palm, and folding it over again.
