Miyazaki Chilled Miso Over Rice (冷や汁, Hiyajiru)

Hiyajiru belongs to the thick part of summer, when even a good appetite needs persuading. A bowl of hot rice waits, and over it goes cold miso broth, savory with grilled fish and sesame, sharp with cucumber and shiso. The temperature shock is not decoration. It is the dish.

People sometimes make this sound rustic in the way that means careless. It isn't. The work is plain, but each plain thing matters: grill the fish so it gives sweetness and smoke, toast the miso so its raw edge disappears, grind both with sesame until they become one paste, then slack it slowly with chilled dashi. Add all the liquid at once and you chase lumps around the bowl like a clerk chasing paperwork. Add it patiently and the broth turns smooth without losing its hand-made texture.

Use fish that's glistening fresh, because there is nothing hidden here. Horse mackerel is common, mackerel is good, sea bream is elegant, and each gives the broth a different weight. The cucumber should be salted and squeezed so it stays crisp and doesn't water down what you built.

In the rhythm of a Japanese meal, hiyajiru is almost a meal collapsing itself into one summer bowl: rice, soup, fish, herb, and vegetable. It is not difficult, only unfamiliar. Make the dashi clean, make the broth cold, keep the rice hot, and the old logic of the dish shows itself without fuss.
