Tips for the Best cucumber and onion salad

What’s the best way to select cucumbers for this salad?
When choosing cucumbers, look for firm ones with smooth, unblemished skin. Medium-sized cucumbers are ideal as they tend to have fewer seeds and a better crunch. If possible, opt for organic varieties, which often have better flavor and less wax coating.

Freezing is not recommended for this salad due to its high water content, which can lead to a mushy texture upon thawing. Instead, prepare only what you plan to eat within a couple of days for the best taste and texture.
What if I don’t have fresh dill?
No worries! If you don’t have fresh dill on hand, you can substitute it with dried dill (use about one teaspoon) or skip it altogether. Alternatively, try adding other herbs like parsley or basil for a different flavor twist!
