Sorrel Stem Soup

I hate throwing food out. For years I pinched the stems off sorrel leaves and chucked them. Then one day as I was cleaning the sorrel, it occurred to me that maybe something could be done with them. I boiled them up, and lo and behold, the liquid in which they boiled had a wonderful flavor of sorrel. At that point I did chuck the stems, but I made a lovely soup—elegant enough for any dinner.
