Cultural layer

Origin

China; douchi, one of the oldest soy fermentation products, predating soy sauce

Routes

Ancient Chinese production, spread across East and Southeast Asian cooking, foundational to Cantonese and Hunanese cuisine

Context

Douchi predates soy sauce, and the reason we can say so is that someone kept a list. Han Tomb 1 at Mawangdui near Changsha, sealed about 165 BCE, held fermented black soybeans with ginger in sealed pottery jars, itemised on the bamboo inventory strips that came with them. That makes douchi the oldest documented fermented soy food, and it unsettles the assumption that soy sauce is the original form. Culinary history tends to privilege whatever was most successfully commodified and exported. Douchi is older and less globally familiar because it was never industrialised for export. The product that won the market is not the same as the product that came first.

The routes are written. They are not yet mapped.

This entry's cultural layer already names where it came from and how it moved. What it does not yet carry is that movement as structure: ordered waypoints with real coordinates, and a mechanism on each leg. Until it does, the layer stays an empty slot rather than a drawn line, because a map built from prose would be a guess with a projection under it.
