thai spinach

Thai spinach, scientifically known as Ipomoea aquatica (and commonly called water spinach, ong choy, or kangkung), is an aquatic or semi-aquatic herbaceous vine native to Southeast Asia. Despite its common English name, it is not a true spinach but rather a member of the morning glory family (Convolvulaceae). The plant features slender, hollow green stems and elongated, lanceolate leaves that grow in clusters along the stems. Water spinach has a mild, slightly nutty flavor with tender leaves and crisp, succulent stems that remain crunchy even when cooked. The entire plant—both stems and leaves—is edible and is prized across Southeast Asia for its delicate texture and subtle vegetable flavor.\n\nThe plant grows quickly in warm, wet conditions and has been cultivated in Asian agriculture for centuries, particularly in regions with abundant water and warm climates. It is sometimes called a "vegetable of the future" due to its rapid growth rate, high nutritional content, and ability to thrive in marginal agricultural conditions.

Thai spinach is a staple vegetable across Southeast Asian cuisines, particularly in Thai, Vietnamese, Chinese, and Filipino cooking. It is commonly stir-fried with garlic, chili, and soy sauce (as in the popular Thai dish pad ong choy) and features prominently in soups, curries, and noodle dishes. The vegetable pairs well with strong aromatics such as garlic, ginger, and fermented pastes. Because the leaves and stems have different cooking times, many cooks slice the tender leaves and hollow stems separately, adding stems first and leaves toward the end of cooking to preserve texture. Thai spinach is best consumed fresh or cooked briefly, as prolonged cooking can make it mushy.
