Item Details

Kai Choy mustard greens, also known as gai choy in Cantonese, is a type of mustard plant. Kai Choy mustard greens are common green vegetables served as a side dish or appetizer. They are full of nutrition and low in carbs. You can braise, saute, blanch, or pickle them. Kai Choy mustard greens are an excellent source of vitamins A, C, and K. They are high in antioxidants and fiber, help lower cholesterol, detox the liver, and blood, and are packed with phytonutrients.


Gai Choy is native to India. The first varietal differentiation, though, was cultivated in China. Gai Choy prefers warm, humid conditions where it will grow prolifically. It is extremely sensitive to freezing and cannot survive at temperatures below 25°F.


Because of its peppery and bitter mustard flavor, kai choy is often blanched in boiling water first to remove some of the bitter taste. The best way to clean these greens is to first, dice them into roughly 1-inch sections, and then thoroughly rinse them in running water.

To store, place the greens in a sealed bag or container and store them for up to three days.
