Can I store raw gnocchi dough in the fridge? I made gnocchi dough earlier this evening. It was my first time, so I took a bit of dough and made myself some dinner with it. It was great.

But I still have some dough left over. Since it's quite late: can I store it in the fridge and continue making gnocchi tomorrow?
Yes, gnocchi store well in the fridge for a day or so, or in the freezer for longer term storage. It's best to try and keep the gnocchi separate (placing on a baking sheet or tray is best) so they don't stick together, and very well covered so that they don't absorb any odours in your fridge.

If freezing, freeze on the tray until reasonably hard, and you can then transfer them to a tub or bag.
