Fegato alla veneziana is calf's liver sliced thin and cooked slowly with a large quantity of sweet white onions, typically close to equal parts liver and onion by weight, softened in butter and olive oil with white wine and a touch of parsley. The dish is traditionally served over soft white polenta (polenta bianca), made from a white corn variety once grown on the lagoon islands. The word fegato, and the use of liver in Italian cooking generally, traces back to the Roman dish iecur ficatum, "fig-fattened liver," made by feeding pigs or geese dried figs before slaughter to sweeten the organ's flavor; the Latin ficatum is also the root of the French foie. Fresh figs were not available year-round in the Venetian lagoon, and by the Renaissance, cooks had substituted the sweetness of slow-caramelized onions, cheap and abundant from market gardens on islands like Sant'Erasmo, for the fig-feeding method. The onion-based version became the standard Venetian preparation, later codified in 19th-century Italian cookbooks, including Pellegrino Artusi's 1891 manual. Today the dish appears on menus at traditional trattorias such as Alle Testiere and Osteria da Fiore, as well as neighborhood bacari that serve smaller cicchetti-sized portions. A full plate at a sit-down trattoria typically costs 16 to 24 EUR, while a small cicchetto portion at a bacaro counter runs just a few euros.
