Creamy Cucumber Salad Recipe

To make the dressing, in a large bowl, combine sour cream, dill, vinegar, sugar, salt, and pepper until well mixed. Refrigerate until the salad is ready to serve. Peel cucumbers, cut them in half lengthwise, and remove seeds; cut them crosswise into thin slices. Thinly slice onion. Fold the cucumber and onion into the dressing. Spoon the salad into a serving dish, and serve immediately.
