These rustic noodles, all thick and chewy and rich with sourdough flavor, are excellent when you serve them with brown butter and fresh herbs. It's also a great way to use up extra sourdough starter.
Pour one cup of sourdough starter into your mixing bowl, and then add the flour and egg yolks. Mix the ingredients together until it forms a ball.
Place the ball on a floured work surface, pat it into a rectangle, and then roll it flat to a thickness of 1/16 of an inch. Cut noodles to your desired shape. Allow them to dry on the counter or boil them for right away.
