Peeled cucumbers are especially delicious. It might feel like a waste but it makes a big difference, so it's definitely worth it.
One salad that I ate at a restaurant had peeled cucumbers in it and it was very delicious, so I tried to copy it. I made Korean-style dressing and mixed it with the salad.
The key is to peel the skin off the cucumbers.
