Wash, dry, and cut the ends off the cucumbers. Place a cucumber between two chopsticks to prevent cutting all the way through. Cut the cucumber at a 45° angle, making thin diagonal slices on the top before flipping it over to make 90° angle cuts. Cut the spiraled cucumbers in half and add them to a large mixing bowl; alternatively, use a mandolin for thin slices.

In a small bowl, whisk together all the dressing ingredients until well combined. Taste as you go and adjust seasonings based on your preference for sweetness and saltiness.

Pour the prepared dressing over the cucumbers in your mixing bowl and mix gently to combine without breaking them apart. Garnish with finely sliced green onion and sprinkle sesame seeds on top for an added crunch before serving.
