Can I store raw gnocchi dough in the fridge?
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.
