The general rule is to let the water be slightly higher than the rice by about 1.5cm~2cm. There is a very easy way to accurately measure the amount of water, use your ring finger to put into the rice water, the water should not exceed the first bone of the ring finger. The amount of water varies slightly due to the origin of the rice and the different tastes of each person. If the steamed rice is too dry, you can add a small amount of water and continue to simmer for a while.
