Knead the pasta, stretching and pressing but not tearing it until it’s super smooth, 8-10 minutes. Wrap the dough in plastic wrap and let it rest at room temperature for 30-60 minutes. If you are not going to use it right away, put it in a resealable plastic bag in the refrigerator for 1-2 days max. (If you don’t use it within 2 days it will start to gray).
