. A cannoli is a Sicilian pastry dessert that is an essential part of the cuisine of Sicily. They are fried, tube-shaped pastry shells filled with a sweet, creamy filling. These treats have a long and storied history and just as many variations. Cannoli originated in Palermo and the surrounding areas. They date to the time when Sicily was controlled by the Arabs. Historically, the pastries were made for the Carnevale, the festival season which occurs immediately before Lent.
