In a mason jar, combine ½ cup sour cream, 1 tablespoon vinegar, 1 tablespoon olive oil, and 2 tablespoons of chopped fresh dill. Season with a pinch of salt and pepper. Secure the lid tightly and shake vigorously for about 15-20 seconds until well blended and creamy.

Prepare the cucumbers by rinsing them under cold water. Peel, halve, and slice them into thin rounds. Also, thinly slice ½ red onion.

In a large salad bowl, combine the sliced cucumbers and red onions, mixing gently.

Pour the prepared dressing over the cucumber and onion mixture. Toss gently to ensure every piece is well coated.

Serve immediately or let it chill in the refrigerator for about 30 minutes for enhanced flavor.
