For best results, allow the dough to rest for at least 30 minutes to relax the gluten, making it easier to roll out. Dust the noodles with flour after cutting to prevent them from sticking together. The brown butter sauce can be adjusted to taste. Add a pinch of red pepper flakes for a little heat, or a squeeze of lemon juice for brightness. Freshly made egg noodles can be stored in the refrigerator for up to 2 days or frozen for up to 2 months. If freezing, arrange the noodles in a single layer on a baking sheet and freeze until solid, then transfer to a freezer bag.
