First of all, according to the variety of rice, in general, high-quality rice uses less water and ordinary rice uses more water. At present, the quality is basically defined as soft rice, that is, rice with low amylose content (below 16%), and rice with high amylose content needs more water and has good water absorption. With the same amount of rice, the rice cooked by high-quality rice is much less than that cooked by ordinary rice (with high amylose content), so ordinary rice is generally used instead of high-quality rice in canteens such as schools and factories. There is a popular saying that rice is increasing, which is the reason.
Secondly, it depends on your needs and preferences. If you like soft rice, put less water. If you like hard rice, put less water.
Under normal circumstances, the rice-water ratio is between1:1-1:1.15, and the high-quality rice is1:1; Ordinary rice 1: 1. 15
