Arancini.Caroline VelikThese rice balls are best served hot and are delicious with a tomato dipping sauce. You can also make them with leftover risotto. If you can't find small bocconcini,use cubes of mozzarella instead. Make sure you season the mix well. Add some fresh herbs for extra flavour. You can freeze or refrigerate them,uncooked or cooked and reheat in the oven.
