My mom always had a bowl of this in the fridge during the summer, and now I do too! My mom sliced her cucumbers and onions in cold salt water for a few hours first, but I usually do not. I do not notice difference when they are not soaked. Instead of peeling the cucumbers completely, I leave a few stripes of green to add color to the salad. Note: Cooking time includes time to chill salad before serving.
