China Kailan, also known as Chinese Kale or Chinese Broccoli, is a versatile leafy vegetable with tender leaves and a thick, crunchy stem that is popular in Asian cuisine. It is often prepared by stir-frying, boiling, or steaming and has a slightly bitter flavor that pairs well with savory sauces like oyster sauce. This crunchy vegetable is also a good source of vitamins A and C, as well as calcium, iron, and potassium.
