Caozaiguo is a type of Chinese candy made from a plant called kudzu root.
So, imagine you are making a cake. To make a cake you need ingredients like flour, sugar, and eggs. Well, to make caozaiguo, you need kudzu root, water, and sugar!
The kudzu root is washed, peeled, and then cut into tiny pieces. Next, it is cooked in boiling water until it becomes a thick, gooey paste. Sugar is added to the paste, and it is stirred until the sugar dissolves.
Once the mixture has cooled, it is carefully molded into small candy shapes. The caozaiguo is left to set, and then it is ready to eat!
So, caozaiguo is like a sweet treat that comes from a plant, similar to how cake is a sweet treat that comes from a bunch of ingredients mixed together.
