Dabei fermented mustard greens use locally grown mustard cabbage as the raw material, fermented naturally with only sea salt through lactic acid fermentation — no preservatives or colorants added. This makes them an important bearer of Taiwan's traditional pickling craft. According to Ministry of Agriculture statistics, Dabei Township accounts for over 80% of Taiwan's total fermented mustard greens production and is known as the "pickled vegetable kingdom." Each year after the winter mustard harvest, the pickling season begins in earnest and the air carries the distinctive aroma of fermenting vegetables.

What are Dabei Fermented Mustard Greens

The process has four steps: sun-wilting, kneading with salt, packing and weighting, and natural fermentation. Mustard cabbage is sun-dried first to remove excess moisture, then rubbed repeatedly with coarse sea salt until it releases liquid, packed into clay crocks or plastic barrels, pressed down with a heavy stone lid, and left to ferment naturally in a cool environment for two to four weeks. The finished product is golden-yellow with a greenish tint, with a crisp bite and a clean, mellow lactic-acid sourness — the ideal supporting ingredient in noodle stall spare rib soup, braised pork rice, and various pork hot pot dishes.

Dabei Township is in the northern part of Yunlin County. Its cool, dry winters are ideal for mustard cabbage growth and low-temperature fermentation. The "Dabei Fermented Mustard Greens Cultural Hall" registered in the Ministry of Culture's Museum Island database is located in Xingan Village; it systematically documents the pickling techniques and industry history, is open to visitors, and is an important site for understanding Taiwan's traditional food preservation culture.

How to eat it the authentic way

🥣
As a side at noodle stallsDabei fermented mustard greens most commonly appear shredded as a side at noodle and rice noodle stalls — the ideal accompaniment to spare rib soup and dry-tossed noodles; they absorb the broth and become even more flavorful.
🥩
Essential in pork hot potPork and fermented mustard green soup is a common home-cooking preparation; the sourness brightens the flavor and cuts the richness — well-suited for braising with pork belly or pork bones.
🛒
How to pick a good oneChoose greens that are golden-green in color and smell cleanly sour with no off odors; avoid anything very dark or with a bitter astringency, which indicates over-fermentation or improper storage.
📅
Buy during peak season for the freshest productNovember through March of the following year is the peak pickling season after the mustard harvest; purchasing directly from Dabei farms or the cultural hall during this window gives the most consistent quality.
