Classic Sicilian Arancini Rice Balls Arancini, rice balls stuffed with sauce peas or corn, are one of the best-loved Sicilian snacks and street foods, and they have become increasingly popular throughout Italy and worldwide. The filling in this recipe is a meat ragù, green peas, and melty mozzarella, but there are endless other types of fillings including pistachios, mushrooms, prosciutto and mozzarella, ham, spinach, and more. The rice is scented with saffron and the rice balls are rolled in breadcrumbs before frying them into balls. Usually, they're made with caciocavallo cheese, but since that can be difficult to find outside of Southern Italy, Parmigiano-Reggiano is used in this recipe. They can be eaten as an antipasto or snack, or even as a meal when coupled with perhaps a salad or soup.
