Supplì are a traditional Italian snack, particularly popular in Rome. They are made from rice, typically cooked with tomato sauce and mixed with cheese, often mozzarella. The mixture is then shaped into small balls, coated in breadcrumbs, and deep-fried until golden brown. These delicious treats are known for their crispy exterior and gooey, cheesy center. Supplì are often enjoyed as an appetizer or street food, and they can be found in many pizzerias and restaurants throughout Italy. They are sometimes compared to arancini, which are similar rice balls from Sicily.
