Italian culinary traditions have often been butchered around the world (see spaghetti Bolognese, post-morning cappuccinos) but next time an Italian scolds you for an Italian culinary offense in your country, remind them that the pesaresi eat pizza with mayonnaise! It's called Pizza Rossini (and Italians from elsewhere have been known to end relationships with pesaresi over it!). Stick with the fresh seafood – best eaten in one of Pesaro's many seaside restaurants!
