5-Minute Cold Cucumber Soup

You’re just minutes away from one of the most refreshing soups on the planet! Unlike most chilled soups, which require hours of refrigeration before eating, this 5-minute cucumber soup can be served straight out of the blender. All you do is throw everything into the blender or Vitamix, and let it do its thing. The key is to make sure that your cucumbers and buttermilk are cold (coming straight out of the refrigerator) before beginning.
