Ohitashi (Blanched Greens in Dashi)
Leafy greens — spinach, chrysanthemum greens (shungiku), komatsuna — blanched in heavily salted boiling water, immediately shocked in cold water to preserve colour, squeezed firmly, and dressed in a small amount of dashi seasoned with soy and mirin. The preparation is deceptively simple and technically precise: the blanch time is measured in seconds, the cold shock is immediate, the squeeze is decisive, and the final dressing is restrained enough to enhance rather than mask the green's natural flavour.

The Method
1
Prepare the ice-water bath in a large bowl before bringing the blanching water to the boil. This is not optional preparation — it must be in place before the greens enter the pot. Bring 4 litres of water to a full rolling boil and dissolve the sea salt into it until the water reaches approximately sea-water salinity.
2
Lower the greens into the boiling salted water. Blanch young spinach for 45–90 seconds; mature spinach or komatsuna for 90–120 seconds. The greens are done when the colour has intensified to a brilliant, vivid green and the leaves yield with slight resistance — not raw-crunchy, not soft.
3
This is where the dish lives or dies. The moment the greens are lifted from the boiling water, transfer them immediately into the ice-water bath. The transfer must be completed within 10 seconds. Chlorophyllase — the enzyme that turns cooked greens olive-drab — activates rapidly in the temperature range between boiling and cold. A 10-second delay produces a perceptible, irreversible colour change. The cold bath must be prepared and within arm's reach; it cannot be improvised after the fact.
4
Leave the greens in the cold water until thoroughly chilled. Remove them and squeeze firmly between both hands, removing the maximum possible moisture. The squeezed bundle should be dense and dry enough to hold its shape when released. Insufficient squeezing dilutes both the dressing and the concentrated flavour of the green itself.
5
Combine the dashi, light soy sauce, and mirin to make the dressing. Cut the squeezed bundles into serving lengths of approximately 4 cm. Arrange in small individual dishes and spoon 2–3 tablespoons of dressing over each portion — enough to coat, never to submerge. The green's own character should be foregrounded; the dressing is a frame, not a covering. The finished dish should taste of concentrated, clean green flavour with a whisper of umami and sweetness.

Quality Hierarchy
01
Reserve — Young chrysanthemum greens (shungiku) at the first cutting, or first-harvest komatsuna — varieties with the highest natural sweetness and the most vivid chlorophyll density, dressed with a single-origin kombu-bonito dashi made to order.
02
Estate — Young flat-leaf spinach from a known grower, with a well-made dashi prepared the same day from quality kombu and katsuobushi.
03
Market — Good-quality baby spinach from a reliable market supplier; a sound dashi made from dried kombu and standard katsuobushi flakes.
04
House — Any fresh leafy green in good condition — spinach, komatsuna, or chrysanthemum greens — blanched and shocked correctly. The technique preserves quality; no ingredient substitution compensates for a failed cold shock.

Sensory Tests
◇Sight. Colour after blanching and shocking is more intensely green than the raw leaf — brilliant and vivid, not dull or olive; this intensification confirms both adequate salinity and a successful cold shock.
◇Touch. The squeezed bundle holds its shape when released and feels dense and dry, not watery or limp; the leaf structure yields with slight resistance under the fingers.
◇Smell. The aroma is fresh and concentrated — the clean scent of the vegetable, not a cooked or sulphurous note, which would indicate over-blanching.
◇Where it lives or dies. The cold shock must be executed within 10 seconds of removing the greens from the boiling water — chlorophyllase activates immediately in the intermediate temperature range, and any delay produces an irreversible olive-drab colour that no subsequent step can correct.
