Cultural layer

Origin

Japan; Eutrema japonicum, long known as Wasabia japonica, growing wild in and beside cold mountain streams; Kew records it native to Japan, Korea and Sakhalin

Routes

Cultivated in flooded mountain terraces, chiefly in Nagano, Shizuoka and Shimane, where the water must hold at 11 to 14 °C all year and the plant takes several years to mature; grown now in South Korea and China as well, with demand rising; outside Japan the fresh root is almost impossible to find, and powder in tins and paste in tubes travel in its place

Context

Wasabi is a plant that cannot leave its water. Tsuji holds that it cannot be cultivated well in anything but cold, pure running water, and in Japan even the greengrocer sells the root standing in a pan of it. It is called Japanese horseradish but is not related to horseradish, and Tsuji finds it more fragrant and less sharp. Outside Japan the fresh root is almost impossible to find, so what travels under its name is a powder in a tin or a paste in a tube. This means that the name travelled further than the plant could.

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.
