Place sliced cucumbers in a colander set over the sink or a large bowl. Toss with 1 teaspoon of salt. Let them sit for 30 minutes to 1 hour to draw out excess water.

After resting, gently rinse cucumbers under cool water to remove excess salt. Press them down with clean hands or pat dry thoroughly with paper towels to remove excess moisture.

In a separate bowl, whisk together sour cream, everything bagel seasoning, white vinegar, and black pepper until smooth.

Step 4: Assemble the Salad

In a mixing bowl, combine the dried cucumbers, sliced red onion, and the dressing. Toss well to coat.

Taste and adjust seasoning with more salt or pepper if needed. Serve immediately or refrigerate for at least 30 minutes for the best flavor development.
