Hubby bought a ten pound bag of russett potatoes because it was on sale for $1.99. We go out of town for a week on Sunday and I don't want to come back to a potato vine growing out of the pantry. I thought I'd make some gnocchi. I've never made gnocchi before. What's the best recipe? Whats the best technique? What should I know before I start? Do I freeze gnocchi after cooking or before? Help!
