General Information: Smooth, shiny, light green stems lead to oval shaped leaves atop. The flavor is similar to bok choy and choy sum, offering the characteristic flavors of cabbage and the spice of radish. Edible Yu Choy is different to the oil seed rape widely grown in the West. Edible Yu Choy is grown mainly for harvesting young leaves and flowering stalks. Plants are picked when bolting and are used in many Chinese stir-fry foods. Yu Choy produces green stalks and tender leaves for cooking uses. A simple steaming is all that is required.
Choy Sum in Chinese means the inner stalks and tips, and thus Yu Choy is also called Green Choy Sum in some regions because Cantonese love to eat the delicious stalks and tips of this vegetable.
