Cultural layer

Origin

Japan, where kombu went to the court as tribute by 715 and dried and boiled bonito were levied as tax under the eighth-century codes; written about widely as dashi from the Edo period, when the Ryōri anbai shū of 1668 puts katsuobushi and kombu into one pot, a stick of the first and two pieces of the second to a shō of water

Routes

Its kombu carried on the kitamaebune from Hokkaido to Osaka, where the best sold first and what was left went on to Edo, that trade and Edo's harder water being the two reasons given for Kansai dashi resting on kombu and Kanto dashi on katsuobushi; taken into the laboratory by Ikeda Kikunae, who traced the taste of kombu dashi to glutamic acid in 1908 and named it umami; sold as the seasoning Ajinomoto from 1909

Context

Ikeda Kikunae began with a bundle of kombu his wife Tei had bought in the spring of 1907, tasting in its dashi what he had met in tomatoes, asparagus, meat and cheese while studying abroad, and in 1908 he traced it to glutamic acid and named the taste umami. His patent was registered on 25 July 1908, and the seasoning, renamed Ajinomoto, was advertised in the Asahi by May 1909. In April 1968 the New England Journal of Medicine printed a letter from Robert H. M. Kwok under the title Chinese-Restaurant Syndrome, and MSG was suggested as the trigger of the symptoms described after a Chinese meal. Ian Mosby, writing in the Social History of Medicine, argues that the syndrome was at its core a product of a racialised discourse, in which assumptions about exotic, bizarre and excessive Chinese cooking meant that few of those studying it questioned its ethnic origins. Geha and colleagues' double-blind, placebo-controlled study of 130 people who believed they reacted to MSG, the largest to date in 2000, found that large doses without food might draw more symptoms than placebo, but the responses were few, inconsistent and not reproducible, and they did not appear when MSG was given with food. The panic was never about chemistry, and it was not really about the letter either.

Route

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.
