01 - In a large mixing bowl, combine the flour and salt. Create a well in the center of the flour mixture.
02 - Add the sourdough starter, eggs, and olive oil (if using) into the well of the flour mixture.
03 - Using a fork, gradually incorporate the flour into the wet ingredients until a shaggy, rough dough forms.
04 - Turn the dough onto a lightly floured surface and knead for 8 to 10 minutes until smooth, elastic, and slightly tacky.
05 - Wrap the dough tightly in plastic wrap and let it rest at room temperature for 1 hour to allow gluten strands to relax.
06 - Divide the dough into 2 equal portions. Working with one portion at a time (keep the remaining covered), roll out using a pasta machine or rolling pin to desired thickness.
07 - Cut the rolled dough into preferred shapes: tagliatelle, fettuccine, pappardelle, or sheets for lasagna and ravioli.
08 - Lightly dust the cut pasta shapes with flour to prevent sticking and arrange in loose nests or lay flat.
09 - Bring a large pot of generously salted water to a rolling boil.
10 - Add the fresh pasta to boiling water and cook for 2 to 3 minutes until al dente. Drain thoroughly and serve immediately with desired sauce.
