Notes
Why salt and squeeze the cucumber: once its water is drawn out, the cucumber stays crunchy and soaks up the dressing much better, and the dressing doesn't get watered down.Use toasted sesame oil, which is dark and fragrant, not cold-pressed sesame oil.Serve as a side with Asian dishes, sushi, or grilled meats.
