water chestnuts

An aquatic tuber (*Eleocharis dulcis*) grown in marshes, prized for a structural uniqueness: it retains a profound, apple-like crispness even after prolonged cooking. Its mild sweetness provides essential textural contrast in rich stir-fries and dim sum fillings. **Selection & Storage:** Fresh water chestnuts are superior but difficult to find; look for firm, unwrinkled tubers. Canned ones are widely available; rinse well to remove any tinny flavor before using.
