Roundup of Italian food history

And then the invaders came along

When the Roman Empire was about to collapse (V century AD), invaders from northern Europe seized the opportunity and went down the boot of Italian peninsula. They brought with them new culinary traditions such as baccalĂ  (salted cod), smoked fish and meat, and casseroles.
At the same time, in southern Italy Arabs introduced almonds, rice, artichokes and spices. Arabs also provided one of the most distinctive features of Italian food, coffee. Still today, the only coffee resembling Italian espresso I could find abroad is Arabic coffee. Dark, strong and prepared with a particular ritual.
At school we were taught that in late Middle Ages, through the birth of the first Comuni and Signorie (local independent communes), a sense of nation was arising for the first time. With them another important aspect of Italian food history was about to be set, regional diversity.
Every large city had a typical dish, cake, cheese or wine. Bologna is famous for its tortellini, Milan for its risotto, the region of Campania for its mozzarella, Tuscany for Fiorentina.
Spanish, French and Austrian influences also played a huge role in the history of Italian food. Tomato is perhaps the vegetable that defines our cuisine. We couldn't even imagine ourselves without it, and was introduced by Spanish conquerors.
Spritz, one of the most famous Italian aperitifs, is said to have been brought along by the Austrian army.
