Supplì al Telefono

Rome, Lazio. Supplì are documented in Roman street food records from the early 19th century. The French word 'surprise' is sometimes cited as etymological origin (a surprise inside) — reflecting French culinary influence in Rome during the Napoleonic period.

Supplì are Rome's street food — rice croquettes made from leftover risotto rice bound with tomato ragù and egg, formed into an elongated oval shape around a piece of fresh mozzarella, coated in breadcrumbs, and deep-fried. The name 'al telefono' ('telephone-style') refers to the mozzarella stretching when you pull the supplì apart — like an old telephone cord. They are sold hot from friggitorie throughout Rome, eaten standing, and must be eaten immediately — the mozzarella sets within 2 minutes.

• Rice croquette with filling, coated and deep-fried — arancini are larger, rounder, and use a more complex filling (meat ragù, peas, or butter-and-mozzarella); supplì are elongated and simpler; both are the street food of their respective cities → Arancini Sicilian
• Fried croquette with a soft, creamy interior surrounded by a crisp breadcrumb shell — different interior (béchamel vs. rice ragù) but the same street food format and technique → Croquetas Spanish

The crisp, golden exterior; the savoury, tomato-rice interior; the stretching, slightly salty mozzarella — the combination of textures (crunchy, starchy, elastic) and flavours (tomato, rice, fresh cheese) makes supplì one of the most satisfying street food bites in Italy. The telephone-cord mozzarella pull is part of the sensory experience.
