You can measure it with your fingers, pour the water after the meal, and measure it vertically with your fingers in the pot. The water is just below the height of the finger sleeve.
This ratio may be difficult to grasp. Another simple way is to put the rice in a pot, add water and put it on the rice with water with a spoon. Water naturally enters the spoon, and the water entering the spoon is flush with the spoon surface, which is the water consumption of steamed rice, which is very accurate.
Pay attention to other places when the meal is delicious. For example, rice should not be washed more than three times. If washed more than three times, the nutrition in the rice will be greatly lost, and the flavor of the steamed rice will also be reduced. Also, after the rice is steamed, the rice cooker will automatically trip to the heat preservation state. If you open it on the spot, the rice may not be in the best condition. Wait 10 minutes before opening the lid. The rice will be delicious.
