The Lombardy region spans a large part of the water-rich Po Valley, and in its various areas one can find food processing plants and dairies. Rice-based dishes such as Risotto, corn-based dishes like Polenta, beef dishes such as Ossobuco, and Christmas cakes like Panettone are just a few examples of the diverse foods from Italy’s wealthiest region. The region’s lakes provide fish, the Alps provide cheeses such as Gorgonzola and Taleggio, and in the Mantua area, sweet pumpkin-filled pasta is a local specialty. Butter is a key ingredient in the local cuisine, and Cotoletta alla Milanese – the local schnitzel – is known worldwide.
