Lotus Root: A Highly Nutritious Aquatic Vegetable Perfect for Stir-Frying or Stewing

Lotus root is the underground rhizome of the lotus plant and a common aquatic vegetable, widely cultivated in the Jiangnan region and the water towns of southern China. Its texture is either crisp or starchy-soft, and it can be eaten both raw and cooked. It works well in cold dishes, quick stir-fries, and stews, making it a very frequent ingredient on home dining tables.

In terms of nutritional composition, lotus root contains carbohydrates and fairly rich dietary fiber, while also providing vitamin C and various minerals such as potassium, copper, and iron, yet its calorie content is not particularly high. Dietary fiber helps promote intestinal peristalsis and aids digestion; the mucilage protein and tannins found in lotus root are also often considered gentle on the stomach and intestines. Cooking it after washing without peeling can also retain more nutrients.

By texture, lotus root can be roughly divided into two types: crisp lotus root and starchy lotus root, and folk tradition often distinguishes them by seven-hole lotus root and nine-hole lotus root. Crisp lotus root has more water and less starch, with a refreshing crunchy texture, suitable for cold dishes and quick stir-fries; starchy lotus root has a high starch content and becomes soft and dense after prolonged cooking, better suited for stewing, steaming, or making lotus root powder.

There are also a few points worth noting when eating lotus root. After cutting, lotus root easily oxidizes and discolors upon contact with air, so it can be soaked in clean water or water with a little vinegar; when boiling lotus root, it is best to avoid using an iron pot, lest the tannins in the lotus root react with the iron and turn the soup black. Mud and sand easily hide in the holes of lotus root, so each hole should be rinsed clean during washing.

Overall, lotus root is crisp, tender, and delicately sweet, with many ways to prepare it. Eaten raw it is refreshing, and cooked it is smooth and warming. Whether for everyday stir-fries or soups, it pairs well with almost anything. By choosing the right variety according to texture and mastering a few simple handling techniques, you can enjoy this taste of the water towns with greater peace of mind.
