Risotto
The principal varieties used in Italy are Arborio, Baldo, Carnaroli, Maratelli, Padano, Roma, and Vialone Nano. Carnaroli, Maratelli and Vialone Nano are considered to be the best (and most expensive) varieties, with different users preferring one over the other. 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 like 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 for making 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.
