Preferably, in the rice cooking process, the cooked rice is obtained such that a rice cooking increase rate (a ratio of a weight of rice after cooking to a weight of rice before cooking) falls within a range of 260% to 280%. More preferably, in the freeze-drying process, the obtained cooked rice is washed, and then the cooked rice is frozen and dried.
