I've been searching for a recipe for this soup. In my memory, it contained bacon, tomato, cucumber, onions, etc. in a thin sour cream base. Delicious!!
Does it ring a bell for anyone?
I’m so glad I could help you out with the white gazpacho, the soup you describe sounds ever so vaguely like Vichyssoise, an absolutely delicious soup that is most commonly made with leeks, onions, potatoes, chicken stock, and cream.
Though it is traditionally served cold (and is wonderful as such), I do prefer mine warm. (My recipe is very similar to the one below, though on occasion I have crumbled a bit of cooked pancetta on top of each bowel, to give the finished dish a hit of smokiness and pork flavour.) http://www.finedinings.com/vichyssoise.htm
