Water spinach

Water spinach (Ipomoea aquatica, Thai pak bung, Vietnamese rau muống, also known as kangkong or morning glory) is a leafy green vegetable native to Southeast Asia. Botanically it is NOT related to true spinach but belongs to the morning glory family, it is a relative of the sweet potato. It has hollow crisp stems and lanceolate leaves with a mild, slightly sweet, faintly nutty flavour reminiscent of spinach. Classic dishes: Thai Pad Pak Bung Fai Daeng (stir-fried with garlic, chilli, and fermented soy bean), Vietnamese Rau Muống Xào Tỏi, and Chinese stir-fries. Briefly blanch or wok-sear before serving.
