This traditional Italian cornmeal owes its humble roots to Northern Italy, where it began as a simple, hearty peasant food. Today, polenta has become a versatile ingredient in Italian cuisine-from the classic, warm and creamy porridge with Parmigiano-Reggiano to a myriad of savory appetizers. When left to cool, polenta "sets" and becomes a sliceable dish to grill, fry or top with sauces.
