Typical Venetian cuisine features fresh, locally sourced ingredients, especially seafood from the surrounding lagoon and seasonal produce. Popular dishes often include fish or shellfish, such as sarde in saor, a dish of sweet and sour sardines, or risotto al nero di seppia, a risotto with black squid ink. Polenta, a cornmeal dish, is also a staple, usually served as a side dish or base for stews. Bigoli, a thick, spaghetti-like pasta, is another regional favorite, often enjoyed with a rich sauce of duck or anchovies.
