Octopus Vinegared Salad (たこの酢の物, Tako no Sunomono)

Octopus makes people hesitate. It looks like a creature with opinions, and the cook begins to imagine special knowledge. For this sunomono, the hard part has usually already been done for you: buy good boiled tako, slice it thin, and let the vinegar do its clean work.

The one detail that decides the dish is the cut. Slice the octopus thinly against the grain, on a slight diagonal, so each piece stays tender and the dressing can reach every face. Cut it thick and it fights back a little. Cut it cleanly and it eats cool, springy, and sweet, with nothing hidden under sauce.

Sunomono means vinegared things, and this one belongs especially well to summer, when cucumber is full of water and the table wants something bright beside rice, soup, and a grilled or simmered dish. We salt the cucumber first because salt pulls out excess water and seasons it from inside; skip that, and the bowl turns watery just when it should be sharp and clear.

The dressing is sanbaizu, literally three-cup vinegar, though no sensible person needs three cups of it at dinner. Rice vinegar, soy sauce, and mirin, with a little dashi to soften the edge, give you brightness, salt, sweetness, and depth in one small bowl. This is honmono made reachable: a chilled salad, a sharp knife, and the nerve to leave it room.
