Whisk together all the ingredients for the sauce in a glass bowl with a lid. You will be using this same container to store the cucumber salad.
Using the back of your knife, gently press on the Persian cucumber on your cutting board and it should smash or crush relatively easy. You want to gently do it as you're not trying to smash it into tiny pieces. It should all still stay in tact. Slice the cucumbers at an angle into 1-inch pieces. Toss the cucumbers in the sauce then cover and put in the refrigerator for up to three days. Toss the cucumbers prior to serving.
