Zeppole or Sfingi has a 2 basic recipe, but one uses potatoes and one uses ricotta. The ricotta version was used by the more higher class. The zeppole was first made in the Middle Ages. I personally love both ways, whether it's potatoes or ricotta. They both bring the true flavor of the original fried zeppole, or else it would just be fried pizza dough. There is also a cream puff pastry version of the zeppole while the this one is more of a fritter. Every year this is made at my church's Italian festival, the church is Saint Rocco's in Cleveland.
