A high-starch (amylopectin), low-amylose round medium- or short- grain white rice is usually used for making risotto. Such rices have the ability to absorb liquids and to release starch and so they are stickier than the long grain varieties. The principal varieties used in Italy are Arborio, Baldo, Carnaroli, Maratelli, Padano, Roma, and Vialone Nano. Carnaroli, Maratelli (historical Italian variety) and Vialone Nano are considered to be the best (and most expensive) varieties, with different users preferring one over another. They have slightly different properties. For example, Carnaroli is less likely than Vialone Nano to get overcooked, but the latter, being smaller, cooks faster and absorbs condiments better. Other varieties such as Roma, Baldo, Ribe and Originario may be used but will not have the creaminess of the traditional dish; these varieties are considered better for soups and other non-risotto rice dishes, and sweet rice desserts. Rice designations of superfino, semifino and fino refer to the size and shape (specifically the length and the narrowness) of the grains, and not the quality.
Risotto / r ɪ ˈ z ɒ t oʊ / ( Italian: [riˈzɔtto] or [riˈsɔtto] , from riso meaning "rice"  ) is a northern Italian rice dish cooked in a broth to a creamy consistency. The broth can be derived from meat, fish, or vegetables. Many types of risotto contain butter, wine, onion, and parmesan cheese. It is one of the most common ways of cooking rice in Italy . Saffron was originally used for flavour and its attractive yellow colour.
