Let me tell you! ! The soup used to top the rice bowl is made of soup stock (classified as bone soup or chicken stock), which is made by adding water to the bones or chicken (nothing else added) and simmering it over low heat. You will definitely ask why the soup is so thick! Let me tell you , because it adds a lot of cornstarch, so there’s no need to mention anything else! Just stir-fry your favorite dish and add soup stock and cornstarch to thicken it!
