Water Chestnut

Water chestnut (Eleocharis dulcis) is an aquatic plant native to Asia, which produces edible tubers commonly used in Asian cuisine. These round, small brown tubers, also referred to as corms, have a white, crunchy texture inside with a mildly sweet taste. They can be eaten raw, boiled, or stir-fried and are packed with nutrients including potassium, magnesium, and various antioxidants. Water chestnuts are often utilized in flavorful dishes ranging from salads and stir-fries to savory fillings for dumplings. They excel at retaining their crispiness during cooking, making them a popular ingredient for adding texture and crunch to various recipes. In Western countries, canned sliced water chestnuts are easily available in supermarkets, making them a convenient addition to home-cooked meals.

Water Chestnut FAQ
Water chestnuts are an Asian vegetable prized for their crisp and crunchy texture. One of the most common misconceptions about this vegetable is that it will soften when cooked. However, water chestnuts retain their crispiness regardless of the cooking method, adding a unique texture to dishes. This makes them perfect for stir-fries, soups, salads, and even desserts. People often use them straight out from the can which is fine, but washing them can reduce the 'canned' taste. Moreover, if they are peeled and used fresh, they offer a sweeter, premium flavor compared to canned ones too. The peeling process might be time-consuming and you need to keep them in water to prevent discoloring but it's worth trying. One little-known trick is to grind water chestnuts into a powder that is often used as a thickener in Chinese cuisine. This provides a subtle sweetness and a smooth, creamy texture to the dishes. Apart from stir-frying, they can also be used in baking and grilling. When baked or grilled, water chestnuts become slightly soft, but mostly preserves it's crunchy bite, that doesn’t yield to a roasting or grilling. They tend to absorb the flavor of whichever ingredients they're cooked with.

Expiration & Storage Tips
When does water chestnut expire?
Unopened canned water chestnuts generally have a shelf life of a year or more past the printed expiration date. After opening, they should be stored in a tightly sealed plastic or glass container in the refrigerator and used within a week. Homemade cooked dishes with water chestnuts should ideally be eaten within 4 to 5 days. Fresh water chestnuts, which may be harder to come by, have a fridge life of about two weeks in the produce drawer. If kept in the freezer, blanched and peeled water chestnuts can last up to a year.
How do you tell if water chestnut is bad?
For fresh water chestnuts, check for sliminess, mold, or an unpleasant smell to tell if they've gone bad. If they have been peeled, they should be white and crisp; any discoloration may indicate that they are no longer fresh. For canned water chestnuts, any sign of contamination—such as swelling or leaking cans, rust, or spoiled smell—means they are not safe to eat. Any mold, sour smell, or change in taste in a cooked dish containing water chestnuts also suggests the dish has spoiled.
Tips for storing water chestnut to extend shelf life
• Store unopened canned water chestnuts in a cool, dry place, away from direct sunlight. • On opening the can, transfer the water chestnuts along with their liquid to a tightly sealing container and refrigerate. • To store fresh water chestnuts, keep them unpeeled in the crisper drawer of your fridge. This maintains their freshness and crunch. • To freeze water chestnuts, first blanch and peel them, then allow them to cool completely. Store in freezer-safe bags or containers with as little air as possible to prevent freezer burn. • When ready to use frozen water chestnuts, thaw them in the refrigerator overnight for best results.
