A folk proverb goes: "Lotus is a treasure, but autumn lotus roots are the most nourishing." Lotus root is not only a good vegetable, but also a good medicine. It contains a large amount of starch, protein, vitamin B, vitamin C, fat, carbohydrates and various minerals such as calcium, phosphorus, and iron. The meat is plump and tender, white and round, and has a sweet and crisp taste. The raw food is comparable to pears and is suitable for nourishing young and old. Cooked food is beneficial to the stomach and spleen, nourishing blood and replenishing deficiency. Seven-hole lotus root is crisp and nine-hole lotus root is glutinous. Seven-hole lotus root is used to make this dish.
