Incidentally, while I do not have the Zuni cookbook,
aschie30's excellent pictorial of her/ Zuni's ricotta gnocchi process is a good approximation for how one makes gnudi. The main differences are: (1) gnudi would typically use semolina flour instead of regular flour; and, (2) after rolling the dumplings in the flour, you'd let them sit in the fridge for a day or two. This allows the cheese to hydrate the flour, so that when you cook them you end up with a thin, smooth, delicate skin that, when it's done right, provides a uniquely sensual dumpling experience.
