fermented black bean

umamisavouryveganvegetarian

Cultural layer

Origin
China, where fermented black soybeans, shi, today douchi, were made by fermenting soybeans with salt and probably existed by 200 BC, the oldest known soyfood in the world
Routes
Traded across Han China, where two of the seven wealthiest merchants of the realm made their fortunes in them; named in Japan's Taihō codes of 701, the earliest document outside China to mention them, and made there by temple monks, as Hamanatto was at Daifukuji on Tokugawa Ieyasu's order of 1605; recorded in the Dutch East Indies in 1900 as tao-dji before they gradually disappeared there, and in the Philippines as tao-si by 1939; most popular today, by far, in southern China, where Yan-kit So's Hong Kong cooking fries them with garlic in oil for black bean sauce
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 in about 165 BC, held fermented black soybeans with ginger in its pottery jars, listed on the bamboo strips buried with them, the earliest completely reliable document of the food. Soy sauce's own precursor, shizhi, a juice drawn from fermented black soybeans, is first named around AD 150. Before that, the History of the Former Han, dated to AD 76, counts two of the realm's seven wealthiest merchants as men who made their fortunes trading it. What this establishes is that soy sauce began as douchi's juice, and that douchi was already making merchants rich before that juice was written down.

Route

Pending

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.

Bonds are drawn from culinary literature and origin-tradition references, tiered by source. Origin means a reference from the place. Witness means the pairing is the place's own and the reference documenting it was written from outside.

The score is cultural weight: how central a pairing is in the tradition that documents it. It is not a prediction of how two materials behave in a formulation and not a measure of chemical affinity. The scale is ordinal, because centrality is a judgement rather than a measurement: 1.0 where the pair is the dish, 0.9 a fixed named form, 0.8 a canonical dish, 0.7 recurrent across many dishes, 0.6 common, 0.5 attested, 0.4 marginal or compound-led.

Each score is set against a named dish and carries that dish in its note. Where a score has not been examined it says so, because an inherited figure and a researched one should not look alike.

The dish is named by a reader who knows the cuisine and cites a source appropriate to it. It has not yet been confirmed inside that source page by page, so a note records what supports a score rather than what has been checked in the book.
