Rice should be moderate, not too little, or the rice soup is not strong enough. Wash the rice clean. If you wash it too much, it won't stick. Soak in water for about half an hour, then pour into the rice cooker, add appropriate amount of water and cook a little more than usual. Press the cooking button of the rice cooker, and pay special attention when the rice grains swell obviously. When the pot boils and the soup thickens, the soup is collected.
