🛒 Ingredients

5 servings

5
  • 1 Japanese cucumber (or thin-skinned cucumber)
  • 1 tablespoon sea salt or Himalayan salt
  • 3 tablespoons rice vinegar
  • 2 tablespoons unrefined sugar (cane or raw sugar)
  • 2 tablespoons white and/or black sesame seeds

Directions

  1. 1

    Rinse the cucumber thoroughly under cold water and pat it dry with a clean kitchen towel.

  2. 2

    Using a mandoline or sharp knife, slice the cucumber into very thin, almost translucent rounds.

  3. 3

    Place the slices in a bowl, sprinkle with salt, and toss well to coat evenly.

  4. 4

    Let rest for 15 minutes — the salt will draw out excess moisture and soften the cucumber.

  5. 5

    Transfer the slices to a colander set over a bowl and drain for 15 minutes.

  6. 6

    Meanwhile, toast the sesame seeds in a dry skillet over medium heat until golden and fragrant. Set aside to cool.

  7. 7

    In a small saucepan, combine the rice vinegar and sugar. Heat gently over low heat, stirring until the sugar fully dissolves. Do not boil.

  8. 8

    Remove from heat and allow the dressing to cool slightly.

  9. 9

    Rinse the cucumber slices briefly under cold water to remove excess salt, then gently squeeze out remaining liquid.

  10. 10

    Pour the dressing over the cucumber, toss to combine, and garnish with toasted sesame seeds. Serve chilled.

💡 Chef's Tip

For an extra crunch, refrigerate the sunomono for 10 minutes before serving. A few slices of pickled ginger or a dash of soy sauce add a lovely umami depth.
