Silky, tender homemade pasta with a delicate sourdough flavor. Simple to make and miles ahead of dried pasta.

Mound the flour on a clean work surface and make a well in the center.
Add the sourdough discard, eggs, olive oil, and salt to the well.
Using a fork, slowly incorporate the flour from the inner walls of the well into the wet ingredients, working outward.
Once a shaggy dough forms, knead by hand for 8-10 minutes until smooth, elastic, and not sticky. Add small amounts of flour if needed.
Wrap the dough in plastic wrap and let rest at room temperature for 30 minutes. This relaxes the gluten and makes rolling much easier.
Divide the dough into 4 pieces. Working with one piece at a time (keep the rest covered), roll through a pasta machine starting at the widest setting, decreasing one setting at a time until desired thickness.
If you don't have a pasta machine, roll with a rolling pin as thin as possible on a well-floured surface.
Cut into your desired shape: fettuccine, pappardelle, linguine, or leave as sheets for lasagna.
Dust the cut pasta with semolina or flour to prevent sticking.
Cook in heavily salted boiling water for just 2-4 minutes (fresh pasta cooks much faster than dried). Taste test early.
Toss immediately with your sauce of choice.
