Ingredients (makes 12)
300g risotto rice (Carnaroli)
700ml beef or chicken broth
100g tomato passata
1 small onion, diced
150g fior di latte mozzarella
50g Parmigiano, grated
2 eggs, beaten
Breadcrumbs to coat
Sunflower oil to fry
Method
1Sauté onion in olive oil until soft. Add rice and toast 1 min. Add passata, then broth ladle by ladle like a risotto. Finish with Parmigiano. Spread on a tray to cool completely — at least 2 hours or overnight.
2Cut mozzarella into 12 small cubes. With wet hands, take a spoonful of cold rice, flatten in your palm, place a cube of mozzarella in the centre, and close the rice around it into an oval shape.
3Dip each supplì in beaten egg, then roll generously in breadcrumbs. For a crispier shell, double-coat (egg → crumbs → egg → crumbs).
4Fry in hot oil (175°C) for 3–4 minutes until deep golden. Drain on paper. Serve immediately — or within 20 minutes while the mozzarella is still melted and stringy.
