Supplì are delicious Roman rice balls that feature a crispy breadcrumb coating and a molten mozzarella center. When pulled apart, the melted cheese creates an appealing stretchy effect that has earned these treats the nickname "supplì al telefono" (telephone-style supplì), as the cheese resembles a telephone cord.

These beloved street food snacks originated in Rome during the 1800s. Initially created as a way to repurpose leftover risotto, supplì quickly became popular at local taverns and food stalls. The name "supplì" comes from the French word "surprise," referring to the delightful cheese surprise found in the center.

Making supplì involves first preparing a flavorful risotto, typically cooked with tomato sauce and seasonings. Once cooled, the rice is shaped around cubes of mozzarella cheese, then coated in beaten eggs and breadcrumbs. The balls are then deep-fried until golden brown, creating a perfect contrast between the crispy exterior and creamy interior.

While traditional supplì are made with tomato-flavored rice and mozzarella, modern variations include different risotto bases like mushroom, saffron, or even carbonara. Some creative versions incorporate different cheeses or additional fillings like meat ragù or vegetables.

In Rome, supplì are typically enjoyed as an appetizer (antipasto) or as a quick street food snack. They're particularly popular as an aperitivo - the Italian happy hour tradition - paired with a glass of wine or beer. You'll find them in local pizzerias, street food vendors, and traditional Roman restaurants.

While undeniably delicious, supplì should be enjoyed in moderation as they are deep-fried and contain cheese, making them high in calories and fat. One or two pieces make a satisfying snack, but they're best shared among friends. For those with dietary restrictions, be aware that supplì contain gluten (from breadcrumbs) and dairy (from cheese), making them unsuitable for those with related allergies or intolerances.
