What Are Mustard Greens?
Learn what Chinese mustard greens are, what they taste like, how they are used fresh or pickled, how to prepare them, and what to substitute.
Mustard greens are leafy brassica greens with a peppery, sometimes bitter flavor. In Chinese cooking, they can be used fresh, salted, pickled, or preserved, depending on the variety and recipe.
Quick Answer
Chinese mustard greens are bold leafy greens used in stir-fries, soups, braises, pickles, and preserved vegetable dishes. Fresh greens taste peppery and slightly bitter, while pickled mustard greens add tangy, savory depth.
What Do Mustard Greens Taste Like?
Fresh mustard greens taste peppery, green, and sometimes bitter. Cooking softens the sharpness.
Pickled or preserved mustard greens taste salty, tangy, and savory. They are often used as a flavor base rather than a plain vegetable side.
What Is Gai Choy?
Gai choy is a common name for Chinese mustard greens. It usually refers to broad-leaf mustard greens with a peppery flavor and sturdy stems.
In English-language markets, gai choy may be sold fresh, salted, or pickled. If a Chinese recipe calls for gai choy, check whether it means fresh mustard greens or preserved mustard greens because the flavor and salt level are very different.
Fresh vs Pickled Mustard Greens
Fresh mustard greens are cooked like leafy greens. Pickled mustard greens are fermented or preserved and used to season soups, fish dishes, noodles, pork, and braises.
Do not treat them as exact substitutes without adjusting salt and sourness.
How Mustard Greens Are Used In Chinese Cooking
Fresh mustard greens can be stir-fried with garlic, blanched, or added to soup. Pickled mustard greens are common in sour fish dishes, noodle toppings, braised pork, and Hakka-style steamed pork.
They pair well with garlic, ginger, pork, fish, tofu, chili, black vinegar, and soy sauce.
How To Prepare Mustard Greens
Wash well and trim tough stems. For fresh greens, cut stems and leaves separately if the stems are thick.
For pickled mustard greens, rinse or soak briefly if they are very salty, then chop before cooking.
Best Mustard Greens Substitute
For fresh greens, use gai choy, kale, chard, bok choy, or collard greens. For pickled mustard greens, use another Chinese preserved vegetable when available.
