About 1 cup of cooked rice is produced from a third cup of dried rice. Most dried rice triples in volume when cooked because rice cooking follows a 2:1 ratio.
While the proportions and cooking times of various types of rice vary significantly, in general, one cup of dried rice provides between 3 and 4 cups of rice when prepared. Medium- and short-grain rice cultivars often yield slightly less than long- and whole-grain kinds. Cook the rice according to the directions on the individual container, or place the rice, water, salt, and butter in a pot. up to a boil. Cover and lower the heat. Usually, two-thirds of a cup of water is used for every cup of dried rice.
