Sichuan fermented broad-bean-and-chili paste, sun-aged 1–3 years. The load-bearing flavor of mapo tofu and twice-cooked pork.
Pixian county (now Pidu district), Chengdu; the workshop dates to c.1688 (Kangxi era) and the method was fixed c.1853 (Xianfeng era) — by tradition traced to a Fujianese migrant, Chen Yixian, whose leftover broad beans grew moldy on the road during the Huguang-to-Sichuan migration; he dried them on a field ridge and ate them with fresh chili. (Salting and the koji-fermentation method came later, defined c.1853 by Chen Shouxin's Yifenghe sauce works.). Pixian doubanjiang earned GI protection in 2005; only paste aged in Pixian's open-air clay vats can carry the name.
Authentic Pixian paste uses erjingtiao chilies, not Korean gochugaru or Mexican guajillo. Chuanlao Hui and Juanchengpai are the two most common GI-stamped brands; look for a numbered crock label.
Brick-red, coarse, oily — visible chili skins and broken bean halves. Salty-savory front, fermented funk middle, slow chili heat at the back. Smell is moldy-sweet, like miso met sun-dried chili.
Two ferments running in one vat: koji-mold broad beans (the umami) and salt-brined erjingtiao chilies (the color and gentle heat). Daily sun stirring drives Maillard browning over years, which is why a 3-year paste reads sweeter than a 1-year.
Variations
Hongyou doubanjiang (red-oil, 1-year, brighter, used for stir-fry); chenpi doubanjiang (3+ years, drier, mortar-ground, for braises and mapo). Dansaniang (single-vat artisan) crocks fetch 4× shelf price in Chengdu.

Ingredients
Serves 6How it's made
4 steps · 35 min active + 365 days 5 min waiting
- 130 min
Mix 1 kg cooked broad beans + 200 g salt + 500 g fresh chili paste in a clay vat.
Watch outGet the salt right at 200g per kilo of beans — too little and the vat spoils before it ferments, so weigh it, don't eyeball it.
- 25 min
Add 30 g qu starter (Aspergillus oryzae); mix; cover with cloth.
- 3525600 min
Sun-cure outdoors during day, indoors at night, 1–3 years; stir weekly.
Watch outStir every week and give it real sun by day — patchy sunning means uneven browning, and the paste never deepens past a dull brick red.
- 45 min
Mature paste darkens deep red and develops intense umami; jar.
Watch outIt's ready when the color's gone deep brick-red and the smell hits you savory and mellow — still pale and sharp-salty means give it more time.
