What is Water Chestnut?

Despite its nutty title, the water chestnut is never a nut but a starchy root crop. Water chestnut plants are cultivated in marshy or wetland regions and can be consumed raw or cooked.

They are mostly known as a popular ingredient in Chinese kitchens. Their flavor is soft and slightly sweet, and they can remain crunchy even after being cooked. Water chestnut is a good source of potassium, fiber, and several healthful antioxidants.

Water chestnut, or Chinese water chestnut scientifically known as Eleocharis dulcis, is a wholesome tuber that belongs to the family of Cyperaceae (sedge) and is indigenous to Asia (Japan, China, India, Philippines, etc.), tropical Africa, Australia, and various islands of the Indian and Pacific Oceans. It is grown in several countries for its edible corms. The Chinese water chestnut may be falsely taken for the European type (Trapa natans) and another Chinese type of water chestnut (Trapa bicornis) which have thick floating leaves and bears a horn-shaped nut. These are not economically relevant and may even become weeds. Water Nuts are some of the accepted common names of Chinese Water chestnuts. Water chestnut is simply not a nut at all, but rather an aquatic vegetable that thrives in mud, marshes, underwater, and has a dainty taste and a crunchy feel that makes it excellent in stir-fries and sautéed vegetable dishes or solely raw in a salad.

Tubers of water chestnut are native to the still, marshy, or slow-moving water plains of South-East Asia.

Water chestnut plant bears plenty, round corms below the soil, which becomes ready for harvest when its leaves are yellowed. The bulbs have coarse dark brown skin, measuring about 5 cm in diameter and 30g in mass. It’s crispy inside, white-fleshed, mildly sweet, and has a pleasant aroma.

Do not confuse Chinese water chestnut with European water caltrops (T. Natans), which is also recognized as western water chestnuts in many markets.
