Perhaps no other country in the world has a cooking style so finely fragmented into different divisions. So why is Risotto typical of Milan, why did Tortellini originate in Bologna, and why is Pizza so popular in Naples? This is so for the same reason that Italy has only one unifying Italian language, yet hundreds of different spoken dialects. Italy is a country of great variety, and Italian cooking is just another aspect of the diversity of Italian culture. This diversity in Italian food stems largely from peasant heritage and geographical differences. Italy is a peninsula separated from the rest of the continent by the highest chain of mountains in Europe. In addition, a long spine of mountains runs north to south down through this narrow country.
