Mozzarella in carrozza

Mozzarella in carrozza (lit. mozzarella in a carriage) is an Italian fried sandwich that's especially popular in Campania, although it's eaten in various parts of Italy. The sandwich is made with crustless, slightly stale bread, mozzarella cheese (ideally di bufala variety), flour, milk, and beaten eggs. Apart from this version, there's also a version with added anchovies. Once assembled, the sandwiches are dipped in flour and cold water (so that the cheese doesn't leak out), then in the beaten eggs, and they're finally fried until nicely browned and crisp on the exterior. This sandwich was invented by housewives in Southern Italy who wanted to make use of leftover mozzarella and stale bread. Nowadays, its popularity has crossed borders, so it's even popular in a few eateries in New York City.
