Yep. Gnocchi is best used within about 2 hours of making it. Store in the kitchen covered gently with a towel before use. Alternatively, you can cook the gnocchi for 30 seconds and then put it straight into ice-cold water to stop the cooking process. Then place on a tray and freeze pieces individually. Once frozen you can pop it into a freezer bag. To cook the gnocchi from frozen just cook for an extra minute or so in boiling water.
