Begin by thinly slicing the cucumbers using a sharp knife or mandoline for uniform pieces. Once sliced, place them in a bowl and generously sprinkle with salt. Let the cucumbers sit for about 15-30 minutes.

After the cucumbers have sat, rinse the slices thoroughly in cold water to remove excess salt. Use a colander to drain the water, then gently pat the cucumbers dry using a clean kitchen towel or paper towels.

In a mixing bowl, whisk together your choice of vinegar and sugar until the sugar is fully dissolved. If desired, add olive oil for richness.

Add the rinsed cucumber slices to the dressing, and toss them gently to coat each slice evenly. Next, incorporate chopped fresh dill and thinly sliced red onion into the bowl.

Cover your bowl with plastic wrap and place the salad in the refrigerator. For the best flavor, let it chill for at least 30 minutes, though overnight is even better.
