Yongfeng chili sauce (永丰辣酱)永丰辣酱
Yongfeng chili sauce is a Hunanese fermented paste of local red lantern chillies with a mould-grown base of wheat, soybean and glutinous rice. Aspergillus moulds first grow on the cooked grain base, which is then mixed with crushed chilli and salt and left in open containers in the summer sun. Yeasts and lactic bacteria then ripen it.

Yongfeng chili sauce is a Hunanese fermented paste of local red lantern chillies with a mould-grown base of wheat, soybean and glutinous rice. Aspergillus moulds first grow on the cooked grain base, which is then mixed with crushed chilli and salt and left in open containers in the summer sun. Yeasts and lactic bacteria then ripen it. Made in 4 steps over 40 days. The longest step, ferment in the summer sun (伏天晒酱), takes 40 days (English Wikipedia). Salt is 9 % (AQSIQ (General Administration of Quality Supe…). Aspergillus oryzae, A. sojae and A. niger and Zygosaccharomyces rouxii do most of the fermenting.
Unlike chilli mashes made from chilli and salt alone, Yongfeng sauce has a mould-grown base of wheat, glutinous rice and soybean, so it ferments like a jiang. It is ripened in open containers in the full summer sun rather than sealed.
Industrial Yongfeng sauceMade to the GI recipe of 50 % chilli and 9 % salt; workshops judge cooking, fermentation and drying by experience.
Safety
The GI text limits the finished sauce to at most 2 % total acid (as lactic acid) and at most 55 % moisture (as drained matter), and gives salt as "≤10-12" % NaCl.
Made in Yongfeng since the Ming dynasty, for more than 300 years. The China Intangible Cultural Heritage Network says Zeng Guofan presented it to the Xianfeng Emperor, after which it became a court tribute product. It is one of Hunan's "three treasures", a Hunan provincial intangible cultural heritage item and a national geographical indication product (approved by AQSIQ Announcement No. 182 of 2007).
