GUNSHO 

Gunsho, or Choi sums, are among the most popular vegetables in Hong Kong, Taiwan, and China. The stems are a vibrant bright green, very sweet and tender, and are usually harvested just before, or as the first few buds are opening. The texture of gunsho is a lot like broccoli rabe but the flavor is much less bitter. 

Gunsho is one of the most nutrient-dense foods in the world, and it is specifically beneficial for its calcium availability. It is lower in oxalate, a substance that binds up calcium and prevents it from being absorbed, than most other leafy greens. It is also abundant in cancer-fighting polyphenols. Like all cruciferous vegetables, more cancer-preventative compounds are produced when gunsho is chopped before using.
