Measure flour directly onto a large wooden cutting board or marble or granite counter top, make a well or volcano in the middle of the flour.
Crack egg and egg yolk directly into the well you just made.
Add a three finger pinch of salt.
Using your fingers or a fork mix egg, gradually bringing in flour, little by little until it forms a shaggy dough.
Begin folding and kneading the dough until it becomes uniform, adding a few drops of water as necessary.
Knead for five minutes, minimum, then cover (airtight) and allow to rest for 30 minutes before rolling out the dough.
