What is Choi Sum? 菜心
Choi Sum (Brassica parachinensis) is a member of the Mustard family, and is also referred to as a flowering pak choy or choy sum. Its green leaves are juicy and tender. If allowed to mature and bolt, yellow flowers will shoot and the plant becomes sweeter and more succulent. The whole plant is edible.
Like Pak Choi, Choi Sum is considered to be one of the most popular vegetables among the Chinese, and is probably the most popular vegetable in Hong Kong. It is now also widely used in the western world and available to buy in most large UK supermarkets.
What does Choi Sum taste like? Well the flavour itself can be described as midway between cabbage and spinach. Choi Sum tends to be blander and closer in taste to cabbage in younger leaves, and develops a little 'kick' in its older leaves.
