01 - In a large mixing bowl, combine the flour and salt. Make a well in the center.
02 - Add the sourdough starter, eggs, and olive oil (if using) into the well.
03 - Using a fork, gradually mix the flour into the wet ingredients until a shaggy dough forms.
04 - Knead the dough on a lightly floured surface for 8–10 minutes, until smooth and elastic.
05 - Wrap the dough in plastic wrap and let it rest at room temperature for 1 hour to allow gluten to relax.
06 - Divide the dough into 2 portions. Working with one at a time (keep the other covered), roll out using a pasta machine or rolling pin to your desired thickness.
07 - Cut into your preferred shape (tagliatelle, fettuccine, pappardelle, or sheets for lasagna/ravioli).
08 - Dust the pasta shapes lightly with flour to prevent sticking.
09 - Bring a large pot of salted water to a boil. Cook the pasta for 2–3 minutes until al dente.
10 - Drain and serve immediately with your favorite sauce.
