What is pak choi?
This member of the cabbage family has a number of different names, including pak choi, bok choy, horse’s ear, Chinese celery cabbage and white mustard cabbage. Its structure looks like a squat celery, with either white or very pale green short, chunky stalks and glossy, deep green leaves.
The texture of both leaves and stalks is crisp, and the flavour is somewhere between mild cabbage and spinach. If very young it can be eaten raw in salads, but is best when briefly cooked.
