Whipped up by a then impoverished widow, Tan Huibin in the 90s to go with her street food noodles, it became famous as she donated meals, poor as she was, to the even poorer. Hence the name “Od Godmother” sauce, Lao Gan Ma, 老干妈. The Post has a story.
It’s not easily available. A similar sauce I’ve been eating daily for years: Guilin Chilli sauce.
[Online, at least for Hong Kong, it’s at Aeoncity.com.hk]
