What is Yu Choy?
Yu choy, also known as choy sum or Chinese flowering cabbage, is a popular leafy green vegetable in Chinese and other Asian cuisines. It is characterized by its tender green stalks, vibrant green leaves, and edible yellow flowers. Though it bears a resemblance to Chinese broccoli (gai lan), yu choy has a milder, sweeter flavor and thinner stalks, making it a versatile ingredient for various cooking methods. Its delicate texture and earthy taste make it an excellent addition to stir-fries, soups, and salads. The entire above-ground portion of the young plant is edible and consumed.
