Typical of the valley north of the Tuscan town of Arezzo called the Casentino, this simple and delicious recipe could not be any easier to prepare. Simply mix ricotta cheese, spinach, grated pecorino cheese, eggs, a small amount of flour and salt and pepper to taste. Then roll into a dumpling shape or round balls and cook in boiling water. Serve with butter and grated Casentino pecorino or Parmigiano Reggiano cheese. Buon appetito!
