Note:
If cucumbers are waxed, they should be peeled first.
In a colander, layer the cucumber slices, sprinkling each layer with a little salt. Mix all together with clean hands and allow to drain for one hour. Rinse well, and set aside to drain while preparing the dressing.
For the dressing, whisk together the sour cream, vinegar, sugar and black pepper. Add dill if using. Adjust ingredients to taste. In a bowl mix cucumber slices, onions, and dressing. Allow to sit in the fridge for at least an hour, 4 is better and even longer is better than that, if possible.
If not salting the cucumbers, add a little salt to the dressing.
