Cold beetroot soup with sour cream

The summer is over, but we still can enjoy cold beetroot soup. I prepared it a few weeks ago, while we still had our own cucumbers and beetroots. I’ve never prepared this soup with sour cream, but it’s really good. So from now on I think I won’t by expensive sour milk that is made specially for this soup, but will buy cheaper and add some sour cream. Because it’s delicious too!
