Bok choy

Bok choy , pak choi (British English, South African English, and Caribbean English) or pok choi (Brassica rapa subsp. chinensis) is a type of Chinese cabbage, used as food. Chinensis varieties do not form heads and have green leaf blades with lighter bulbous bottoms instead, forming a cluster reminiscent of mustard greens. It has a flavor between spinach and water chestnuts but is slightly sweeter, with a mildly peppery undertone. The green leaves have a stronger flavor than the white bulb. Chinensis varieties are popular in southern China, East Asia, and Southeast Asia. Being winter-hardy, they are increasingly grown in Northern Europe.[citation needed] Now considered a subspecies of Brassica rapa, this group was originally classified as its own species under the name Brassica chinensis by Carl Linnaeus.[citation needed] They are a member of the family of Brassicaceae or Cruciferae, also commonly known as the mustards, the crucifers, or the cabbage family. Other than the ambiguous term "Chinese cabbage", the most widely used name in North America for the chinensis variety is simply bok choy (Cantonese for "white vegetable") or siu bok choy (Cantonese, for "small white vegetable"; as opposed to dai bok choy meaning "big white vegetable" which refers to the larger Napa cabbage). It can also be spelled pak choi, bok choi, and pak choy. In the UK, South Africa, and the Caribbean the term pak choi is used. Less commonly, the descriptive English names Chinese chard, Chinese mustard, celery mustard, and spoon cabbage are also employed.
