The main ingredient in risotto is Arborio rice. This short-grain rice variety is prized for its high starch content, which gives risotto its characteristic creamy texture. Arborio rice absorbs flavors well and cooks slowly, requiring gradual addition of stock while stirring to release the starch. This technique allows for the creation of a rich, flavorful dish that can be customized with a variety of ingredients, such as vegetables, proteins, and cheeses. Risotto is a traditional Italian dish, showcasing the importance of quality rice in achieving its signature consistency.
