Cannelloni are rectangular pasta sheets that are rolled into a cylindrical shape encompassing a filling. After a pasta sheet has been boiled, it is typically filled with a savory stuffing which may include ricotta cheese, spinach, and various meats. It is then covered with a sauce, typically a classic tomato or béchamel sauce. Cannelloni is often erroneously referred to as manicotti, which is actually a filled Italian dinner crepe, as opposed to pre-rolled pasta. While many Americanized versions believe manicotti and cannelloni are interchangeable, traditional Italian dishes make cannelloni with pasta and manicotti with a specialized crepe pan. Although both terms are plural nouns in Italian, the English term is often construed as singular, particularly when used as the name of the dish.
