Fontina is a semi-soft cheese that originates from the Aosta Valley in the Italian Alps. It is made from cow's milk and is known for its rich, creamy texture and nutty flavor. The cheese has a pale yellow color and is often characterized by its small holes, which develop during the aging process. Traditionally, Fontina is aged for at least three months, but some varieties can be aged longer for a stronger taste. It is commonly used in cooking, especially in dishes like fondue, risotto, and creamy sauces, making it a popular choice in Italian cuisine.
