Risotto balls, also known as arancini, are a popular Italian appetizer made from leftover risotto. These crispy and golden balls are filled with gooey cheese and can be served as a snack or a side dish. The risotto is formed into balls, stuffed with cheese, coated in breadcrumbs, and then deep-fried until crispy. The result is a delicious combination of creamy risotto and melted cheese, with a crunchy exterior. These arancini balls are perfect for parties or as a tasty snack any time of the day.
