Route
PendingThe 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.

Ichiban dashi.
The defining case of umami synergy. Kombu carries free glutamate, katsuobushi carries inosinate, and the two multiply rather than add: each is modest alone and together they produce a savouriness far beyond the sum. Kuninaka identified the effect in 1957, Ikeda had isolated the glutamate in 1908, and Japanese kitchens had been making the stock for centuries before either.

Glutamate in the kombu and 5'-guanylate in the dried shiitake are weak apart and multiply together: the ribonucleotide raises the perceived umami of the glutamate far beyond the sum. Kuninaka identified the effect in 1957, working with dried shiitake, half a century after Ikeda isolated the glutamate from kombu. Both sit inside the tradition that built dashi on the combination first.

Miso soup, built on kombu dashi.
Yudofu, simmered in kombu water.
Ponzu steeped with kelp, and sushi rice cooked with kelp before the vinegar goes in.
Cod hotpot, simmered over a square of kelp.
Two things cross the same contact in opposite directions. The dried kelp pulls water out of the fish by osmosis, which firms the flesh and turns it translucent, while the kombu's free glutamate travels the other way into it. The fish ends up drier and more savoury than it began, without heat, salt or a pot. It is the dashi relationship run as a cure rather than a broth.

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.
