01 - In a large mixing bowl, combine the flour and salt. Make a deep well in the center.
02 - Add the sourdough starter, eggs, and olive oil (if using) into the well of flour.
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 firmly for 8–10 minutes until smooth, elastic, and no longer sticky.
05 - Wrap the dough tightly in plastic wrap and let 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 other covered), roll out using a pasta machine or rolling pin to your desired thickness.
07 - Cut the rolled dough into your preferred shape: tagliatelle, fettuccine, pappardelle, or sheets for lasagna and ravioli.
08 - Dust the cut pasta shapes lightly with flour and arrange in loose nests or separated layers to prevent sticking.
09 - Bring a large pot of generously salted water to a rolling boil.
10 - Add the fresh pasta to the boiling water and cook for 2–3 minutes until al dente. Fresh pasta cooks quickly, so taste-test after 2 minutes.
11 - Drain the pasta thoroughly and serve immediately with your favorite sauce. Toss with sauce right away to prevent sticking.
