What is Choy Sum and how is it different from other Asian greens?
Choy Sum, also known as Chinese flowering cabbage, is a type of Asian green that belongs to the Brassica family. It is a cool-season crop that is widely cultivated in China and other parts of Asia. Choy Sum is characterized by its delicate, tender stems and leaves, as well as its small, yellow flowers that bloom in the center of the plant. Unlike other Asian greens, Choy Sum has a milder flavor and a more delicate texture, making it a popular choice for stir-fries and other Asian dishes.
One of the key differences between Choy Sum and other Asian greens is its unique growth habit. While other greens like bok choy and Chinese broccoli have a more compact, dense growth habit, Choy Sum has a looser, more open growth habit that allows for better air circulation and sunlight penetration. This makes Choy Sum more resistant to disease and pests, and easier to grow in a variety of conditions.

Unlike Choy Sum, Mustard Greens have a more robust, pungent flavor and a coarser texture, making them a popular choice for heartier, more flavorful dishes.
One of the key differences between Mustard Greens and Choy Sum is their flavor profile.

It’s also important to note that both Choy Sum and Mustard Greens can be eaten raw, and are often used in salads and other cold dishes.
