All the fresh herbs make this cold soup marvelously refreshing. Key ingredient is raisins. Absolutely perfect if you have an herb garden; otherwise, for those of us who don't, a little expensive to prepare (unless you have use for all those extra fresh herbs) but great on the tastebuds and wonderfully aromatic nevertheless. Substitute dried for fresh if fresh herbs unavailable. I prepared this for a 3-day July 4th weekend. Cut out of an article in the NY Times, adapted from Najmieh Batmanglij, a Thai chef living in the U.S., but she described this as a Persian soup. Cooking time is chilling time.
