Thanks so much for the hints. It must have been such a treat to learn from your grandmother. I've made gnocchi from regular potatoes before. I was wondering whether it's necessary to change the flour ratio when you use sweet potatoes because they have a different starch content. Also, I've never used ricotta in gnocchi, but have seen a sweet potato recipe that calls for ricotta. I imagine the ricotta would make the gnocchi very light, but I don't want to lose any of that wonderful sweet potato flavor. Have you ever made gnocchi with ricotta? Thanks so much.
