Sichuan Chili Bean Paste (Doubanjiang) Production
Pi Xian county, Sichuan Province — designated Protected Geographical Indication product
The making of Pi Xian dou ban jiang: broad beans inoculated with mould, then combined with dried chili and salt in clay crocks to ferment for months to years in the sun and rain of Pi Xian county. The longer the fermentation (1–3 years optimal), the deeper the umami, colour, and complexity. The soul of Sichuan cooking.
