Spring Sansho Miso (木の芽味噌, Kinome-miso)

Kinome arrives in spring as a small leaf with a large opinion. Rub one between your fingers and you get green citrus, pepper, and a quick clean tingle, gone almost before anyone can become tiresome about it. That briefness is the point. This paste belongs to the week when the leaves are tender and bright, and if you miss it, you don't fake it with powder. You make the base and wait for 旬 (shun) to come around again.

Kinome-miso looks like a specialist's sauce because it is green, glossy, and usually appears beside bamboo shoots or sea bream on a very careful plate. The work is calmer than that. You make tamamiso, an egg-yolk-enriched sweet white miso, cook it gently until glossy, cool it, then grind in the leaves. The one detail that decides it is temperature: add kinome while the miso is hot and the perfume fades, the color dulls, and spring leaves the bowl.

Use it thinly. Brush it on grilled takenoko (bamboo shoots), sea bream, or tofu, enough to scent the surface and no more. This is not a sauce for burying food; it is the season speaking from a small place. Leave it room, and it will do more than a heavy hand ever could.
