How it's used
Refers specifically to the younger, more tender variety of mustard greens, which are prized for being less bitter than the mature, larger leaves. It is a staple in home-style Cantonese soups and stir-fries, often paired with salted duck eggs or ginger to balance its natural pungency. Unlike the larger, fibrous stalks, these are often cooked whole or just halved.

Common mistake
Do not confuse this with 菜心, which is a different vegetable entirely. While both are leafy greens, 芥菜仔 has a distinct, slightly spicy or bitter profile that is absent in the milder 菜心.
