Sunomono (cucumber salad) with rice vinegar and sesame

Sunomono, meaning vinegared things, is the crisp, cooling salad that Japanese cooks serve alongside grilled fish and rich dishes to refresh the palate. Cucumber is the most familiar version, sliced thin, salted to draw out the water, and dressed with rice vinegar, sugar, and a whisper of soy. Chefs say a good sunomono should wake up your appetite, not fill it, and it belongs on every summer table, ready in minutes with barely more effort than opening a bag of salad.

Bright, tangy, and bracingly cold

Each slice stays snappy and cold under a sweet-tart dressing that cuts straight through rich food, finished with toasted sesame seeds and a hint of ginger. It is the kind of side dish that makes the whole meal feel lighter and cleaner, and it keeps well for a day if you hold the dressing until serving. Salt the cucumbers first and squeeze them well, or the dressing will water down into a sad puddle at the bottom of the bowl.

Step by stepInstructions

  1. Toss the cucumber slices with the salt in a bowl and let sit for 10 minutes.
  2. Squeeze the cucumbers gently to remove the excess water.
  3. Whisk the rice vinegar, sugar, soy sauce, sesame oil, and ginger together until the sugar dissolves.
  4. Add the cucumbers and the wakame, if using, and toss well.
  5. Sprinkle with sesame seeds and serve chilled.

💡 Chef tips & storage

Salting and squeezing the cucumber first is the step that keeps the dressing from pooling. The same dressing works beautifully on sliced daikon, carrot, or shredded cabbage.
