All you’ll need to whip up a quick, delicious Japanese cucumber salad are 2 medium cucumbers, 1/4 cup rice vinegar, 1 teaspoon sugar, 1/4 teaspoon salt and 1 tablespoon toasted sesame seeds. Slice the cucumbers in half, lengthwise. Using a food processor or sharp knife, cut into very thin slices. Place the slices in a double layer of paper towel and squeeze gently to remove any excess moisture. Mix the vinegar, sugar and salt in a medium bowl, stirring to dissolve. Add the cucumbers and sesame seeds; toss well to combine. Serve immediately.
