Gai Lan closely resembles another Asian cabbage known as Choy Sum. With very small white flowers rather than yellow near its stems, the entire vegetable, including the flowers can be boiled, steamed and stir-fried.
Gai Lan (Chinese Broccoli)
Similar to a flowering broccoli, Gai Lan has very dark green leaves and slender green stalks. Sometimes a substitute for kale, Gai Lan has a pleasantly bitter flavor reminiscent of Choy Sum and is used in soups and vegetable dishes.
