Risotto is a creamy Italian dish made with Arborio rice, butter, and various ingredients such as cheese, meat, or vegetables. It is typically cooked slowly, allowing the starch in the rice to thicken the liquid. Arborio rice is a short-grain rice that is commonly used for risotto due to its ability to absorb liquid and remain creamy when cooked. It is also used in other dishes such as pilafs and puddings.
