The secret to this incredible cucumber salad is salting the cucumbers for 30 minutes. As they sit, the cucumbers become even more “cucumbery” and release extra moisture, which, if not removed, would make the vinegar dressing watery.
2 hot house or seedless cucumbers, about 1 ½ pounds
Salt
2 to 3 teaspoons granulated sugar, depending on taste
1/4 cup (60ml) apple cider vinegar or distilled white vinegar
2 teaspoons Dijon mustard
1/4 of a medium red onion, thinly sliced
Thinly slice cucumbers, toss with two teaspoons of salt, then add to a colander set over the sink or bowl. Let sit for 30 minutes.
Rinse the cucumbers with cold water, then squeeze out excess water. To make this easy, we add the cucumbers to a clean dish towel, tie it up, and squeeze.
Whisk together two teaspoons of sugar, vinegar, and mustard in a large bowl. Taste, then add the additional teaspoon of sugar if needed.
Add the cucumbers and red onion, then toss. Enjoy immediately, or refrigerate up to a day before serving.
