This recipe is a meticulously calibrated blueprint designed to produce predictable texture and deep sourdough flavor in homemade pasta every single time, moving beyond standard egg pasta techniques.
The lactic acid in the starter changes the elasticity; you must trust the 10-minute machine time to properly align gluten. Do not add salt or oil to the dough mix; season the cooking water heavily instead. If using a fed starter, the flavor will be milder; use long-stored discard for a sharper tang. For vegan/egg-free substitutions, allow 4 tbsp ground flax + 12 tbsp water to gel for 15 minutes, and increase the initial rest time to 1 hour.
