You can refrigerate homemade noodles for up to 1 day or freeze for up to 1 month. To dry your noodles, arrange in a single layer on a lightly floured surface or clean kitchen towel. Let them stand at room temperature for 12 to 24 hours, depending on the humidity and temperature of your kitchen. (A fan set to low speed directed at the noodles will speed this process.) When a noodle snaps instead of bends, you know it's properly dried. Dried fresh pasta will last 2 months or more when stored at room temperature in an airtight container.
