Water Spinach, aka “ong choy” is one of the most popular green in Vietnamese and Chinese cooking. There are so many sauces to accompany this vegetable that offers both tenderness and crunch. In Cantonese cooking, fermented shrimp paste is often used to stir fry water spinach. In Vietnamese cooking, it is stir fried in garlic and fish sauce or simply boiled and dipped into a prepared sweet and savory fish sauce. I chose to use miso paste and garlic for some umami. Stir fried water spinach is a lovely addition to a simple weeknight dinner. It’s quick, easy, and very healthy.
How to Prepare Asian Leafy Green Vegetables
Always wash your produce before consuming it. Asian leafy green vegetables such as water spinach contain lots of dirt on their stems. Moreover, you want to wash off as much of the pesticides as possible. For most Asian leafy greens, you’ll want to submerge the vegetables completely in a large bowl of cold water. Slosh them around gently. Then, lift your vegetables up from the bowl of water to leave the dirt and impurities behind. Repeat at 1-2x depending how dirty your vegetables are. Usually, spinach and taku choy have the highest levels of dirt and require lots of washes. Once your veggies are clean, place them into a colander to drain for at least 10 minutes. Then start making your stir fried water spinach.
