Shanghai bok choy – often referred to under the generic moniker “baby bok choy” – is a small variety of bok choy bred for petite size, smooth leaves, tender texture, and mild flavor. Bok choy is a type of cabbage native to China, now popular throughout the world. Unlike common bok choy, which has wide white stems and can be found in both large and baby form, Shanghai bok choy has jade green stems and is found only in the petite form. Despite their common name, Shanghai bok choy are fully-grown at harvest. Usually around six inches in length, Shanghai bok choy has a bulb-like base of clustered stems with oval, flat leaves. The stems and leaves are crisp when raw and become buttery tender when cooked. They have a mild, sweet vegetal flavor with hints of pepperiness (compared to the mineral-forward and distinctly cabbage-like flavor of regular bok choy).
