Begin by washing your medium cucumbers thoroughly under cold water. Using a sharp knife or a mandoline slicer, cut the cucumbers into thin slices, about 1/8-inch thick.

Transfer the sliced cucumbers into a spacious bowl and generously sprinkle them with sea salt. Allow the cucumbers to sit undisturbed for about 10-15 minutes.

In a separate bowl, whisk together 1/4 cup of rice vinegar, 1 tablespoon of granulated sugar, and 1 teaspoon of sesame oil until the sugar fully dissolves.

After the cucumbers have released their moisture, rinse them under cold water in a colander to remove excess salt.

In a large bowl, combine the drained cucumber slices with the prepared dressing. Garnish with toasted sesame seeds.

Transfer the salad into serving dishes. Serve right away or refrigerate for about 15 minutes for enhanced flavor.
