Part of the clean purple-black skin on the water chestnut epidermis is preserved because it contains trace elements such as phosphorus, which can increase the lavender pigment in soup and increase people's appetite.
There is no regulation on the amount of boiled water. Of course, more water makes the soup heavier, and vice versa. Boil it with high fire first, and then stew it with low fire for about ten minutes. Don't drink in a hurry. Let the water chestnut "stuffy" in the pot for an hour to make the soup more "thick".

When I cooked water chestnut soup, I put a small amount of rock sugar and medlar, which was delicious.
