Kailan, also known as Chinese Kale, is a robust leafy green with flat, glossy blue-green leaves and thick stems. This variety is celebrated for its strong, slightly bitter, and sweet flavor profile that stands up well to powerful seasonings like garlic, ginger, and oyster sauce. It is most commonly prepared by blanching or stir-frying, which tenderizes the stems while keeping a pleasant bite. A highly nutritious and flavorful green, it is a staple in Chinese restaurants worldwide.
