2 large cucumbers, sliced thin
1 medium onion, sliced thin
4 tablespoons cider vinegar
2 rounded tablespoons sour cream
1 1/2 tablespoons granulated sugar
Pepper to taste
Place cucumber slices in bowl, salt generously. Set in the refrigerator. Remove from refrigerator after 1 hour and drain off the salted water. Squeeze the cucumber slices to drain additional water. (The salting is optional. It is done to remove some of the moisture from the cucumber so as to prevent thinning of the cream dressing. Whether or not to do it depends on the moisture content of the cucumbers being used. When in doubt, salt.)
Mix together the cucumbers and onions. Combine the vinegar, sour cream, sugar and pepper, making sure that the sugar is dissolved. Pour dressing over the cucumbers and return to refrigerator for several hours.
Will keep in refrigerator for up to 1 week, although the dressing will become thin as cucumbers lose their moisture.
