This widely popular and extremely versatile group of dishes consists of a base of rice and stock. Butter, saffron, and parmesan are some of the ingredients most often combined with the base to make a variety of flavorful risottos. The history of the dish is rife with conflicting theories about its origins, however, it is certain that rice was first introduced to Italy by the Arabs during the Middle Ages.
Since the Mediterranean climate was perfect for growing short-grain rice, huge amounts of it started to be sold – primarily in Venice, Genoa, and the surrounding areas. As rice gained in popularity, it became a staple food of the Po valley, Lombardy, Piedmont, Veneto, and the city of Milan.
It was only a matter of time before rice was combined with saffron, which the Milan region was famous for, and the legendary risotto alla Milanese was invented. Even today, risotto is still usually prepared using the same key components: rice, stock, butter, wine, parmesan, saffron, and onions.
The dish is served throughout the world, so there are also a number of varieties with ingredients such as truffles, squid ink, asparagus, sausage, scallops, and veal, among many others. / tasteatlas.com/risotto
