Gnudi are little dumplings, like gnocchi, but made with ricotta instead of potatoes. Most places don’t do gnudi justice. They are often mushy and heavy, instead of light and fluffy, like these. This recipe makes 36 to 40 gnudi, or enough for 6 to 8 people as a first course. The dough does not keep well, so you need to plan on serving a crowd, or serve hearty, main-dish size portions.
