When I was writing the manuscript for Florentine, I enlisted the help of an army of recipe testers — about 80 people from all over the world — to test every recipe thoroughly. Only one came back to me consistently with problems. From Minnesota to Melbourne, three testers wrote to me that their very first attempt at making Tuscan gnudi (ricotta and spinach balls that, rather than be encased in pasta like for ravioli, are simply dusted in flour) resulted in a pot of simmering water with “dissolved” gnudi.
