Pescado frito is also consumed as a delicacy in inland Spain, being very common in the inland Andalusian provinces of Seville and Cordoba. It is also very common throughout the Mediterranean Basin and is found in Provence and Roussillon, France and in the coastal regions of Italy (where the most common variant using salt cod fillets is known as filetto di baccalà) and Greece (where various fish like Mediterranean sand smelt, European anchovy, cod, common sole, greater amberjack and picarel are used). It was also eaten by the Romans in ancient Rome.
It is made by coating the fish (usually a white fish) in flour and deep-frying it in olive oil, then sprinkling it with salt as the only seasoning. It is usually served hot, freshly fried, and can be eaten as an appetizer (for example with a beer or wine), or as the main course. Usually, it is served with fresh lemon, which is squeezed over the fish or occasionally in escabeche.
It is also a traditional Shabbat fish dish (usually cod) originating amongst the 16th century Andalusian Jews of Spain and Portugal. The deep-frying of the fish in vegetable oil makes it crisp and light even when eaten cold, and it is a favourite dish for the late breakfast or lunch after synagogue services on Saturday morning.
There is a general belief that pescado frito was possibly an inspiration for the English fish and chips, brought to England by Spanish Jews; Sephardim began to settle in England in small numbers in the 16th century, and in larger numbers after Oliver Cromwell lifted the formal ban in the 1650s.
