Sunomono and Dressed Vinegar Preparations

Sunomono—literally 'vinegar things'—is a category of dressed Japanese preparations in which vegetables, seafood, and seaweed are lightly dressed with sanbaizu (three-component vinegar dressing: rice vinegar, soy, mirin) or nihaizu (two-component: rice vinegar and soy) and served as a palate-cleansing, appetite-stimulating first course or side dish. The category encompasses some of Japan's most elegant and refreshing preparations: cucumber and wakame seaweed sunomono (kyuri to wakame no sunomono—the benchmark summer preparation); vinegar-dressed jellyfish (kurage no sunomono) with cucumber; red and white kohaku namasu (daikon and carrot julienne in dressing, served at New Year); and vinegar-dressed seafood including octopus, clam, and crab. Sunomono's cultural function parallels French acidulated salad in cleansing the palate and stimulating appetite, but the Japanese dressing tradition uses rice vinegar's low acidity (4–4.5% vs. Western vinegar's 5–8%) to achieve delicate balance rather than assertive tartness. The preparation is assembled at the last moment to maintain vegetable texture; served cold in summer; sometimes slightly warmed in winter.
