As the saying goes, porridge made with a quick fire, meat with a slow fire. It is best to wait until the water boils before adding rice, so that the porridge will taste delicious. Do not soak the rice beforehand. The soaked rice will not be fragrant when cooked. It is similar to cooking porridge over a slow fire and will affect the taste.
If adding beans, it is best to soak the beans until soft and then mix them with rice and add them to boiling water.
