Water Chestnut
Description
Water chestnuts, or Eleocharis dulcis, are not true nuts, but rather the corms of an aquatic vegetable that grows in marshes, ponds, paddy fields, and shallow lakes. They are revered in various cuisines for their unique crunchy texture and subtle, slightly sweet flavor. When peeled, these tuber-like corms have a crisp white flesh that can be enjoyed raw or cooked. Water chestnuts are a popular ingredient in Asian cuisine, particularly in Chinese dishes, where they are known as biqi or mǎtí in Mandarin.
Common uses
Water chestnuts are commonly used in salads, stir-fries, soups, and as a crunchy addition to stuffings and dumplings. They are also frequently found in Asian-inspired appetizers and can be served as a snack when candied or pickled.
