Medium-grain rice is a type of rice that falls between short-grain and long-grain varieties in terms of size. Typically, medium-grain rice is about 5.5 to 6.5 millimeters long and has a slightly sticky texture when cooked. This makes it ideal for dishes that require a creamy consistency, such as risotto or paella. Common types of medium-grain rice include Arborio and Bomba. These varieties absorb flavors well and are often used in recipes that benefit from a moist, tender texture. Medium-grain rice is popular in various cuisines, particularly in Mediterranean and Asian dishes.
