I was so surprised when I found this recipe. It's made with fresh green beans, and uses potatoes to thicken it instead of flour or cornstarch. I especially like the tarragon in this soup. If it gets too thick, use the larger amount of whipping cream. To save calories, I like to use fat-free half and half. This was in a box of my mother's clipped recipes. I don't know where she clipped it from....looked like magazine paper to me.
