Japan — sunomono tradition documented from ancient times as a refreshing complement to savoury rice-based meals
Sunomono (酢の物, vinegar-dressed things) is the category of Japanese vinegared preparations that occupies the space between a pickle and a salad — marinated briefly in sanbaizu (三杯酢, three-cup vinegar: equal parts rice vinegar, soy sauce, and mirin) or niban-zu (二杯酢, two-cup vinegar: rice vinegar and soy without mirin). Unlike tsukemono (fermented pickles), sunomono is dressed immediately before serving with the acid providing brightness rather than fermented complexity. Standard sunomono preparations: kyuri no sunomono (cucumber dressed in sanbaizu with wakame seaweed and tiny shrimp — the archetypal version); tako su (octopus sunomono, thin-sliced boiled octopus with wakame in sanbaizu); kani sunomono (crab meat with cucumber); and mozuku-su (a native Okinawan seaweed dressed in a light vinegar tare served as a small cold starter). The technique requires: salting vegetables first (shio-furi, 塩振り) to draw excess moisture that would dilute the dressing; squeezing out the drawn moisture before dressing; and applying the sanbaizu only immediately before serving, never in advance. The acidity perception in sunomono is calibrated to the season: summer sunomono is more acidic (higher vinegar ratio) to provide refreshment in heat; winter sunomono is gentler and sometimes includes dashi to add warmth. Amazu (甘酢, sweet vinegar — more sugar, less soy) is used for a softer, less sharp variant appropriate for wagashi-influenced presentations.

{"Salt-squeeze-dress sequence: shio-furi (salt) → rest 10 minutes → squeeze → dress with sanbaizu immediately before serving","Sanbaizu ratio: equal parts rice vinegar : soy sauce : mirin is the baseline — adjust to season (more vinegar in summer; more mirin in winter)","Pre-dressed sunomono goes soggy — dress only immediately before serving; a prepared but undressed sunomono can be held refrigerated for up to 2 hours","The vinegar in sanbaizu must be rice vinegar (komezu) — other vinegars (apple cider, white wine) lack the clean, gentle acidity that defines Japanese sunomono","Wakame preparation for sunomono: dried wakame rehydrated in cold water for 10 minutes, then squeezed; fresh wakame blanched 30 seconds and shocked in ice water — both must be completely drained before dressing"}
{"A small amount of freshly grated ginger added to sanbaizu immediately before dressing provides a summer-enhancing heat that complements both seafood and vegetable sunomono","Mozuku (a slippery, thread-like brown seaweed from Okinawa) dressed in a dashi-enriched amazu is the purest expression of sunomono — the seaweed's natural viscosity thickens the dressing slightly, creating a coating that clings","Adding a few drops of sesame oil to sanbaizu at the final moment before dressing produces a Chinese-inflected sunomono that bridges Japanese and Chinese culinary conventions while remaining distinctly Japanese"}
{"Skipping the salt-drawing step for cucumber — undrained cucumber dilutes the sanbaizu dramatically and produces a wet, insipid sunomono","Using regular white vinegar instead of rice vinegar — white vinegar's harsh acidity is incompatible with the gentle, sweet-sour balance of authentic sanbaizu"}
