I loved the fresh tangy herby flavor of this soup! For the plums I used small green Santa Rosa plums that had blown off my tree in the wind...they reminded me of tomatillos. I used thinly sliced sirloin I had on hand and fresh herbs. This was even better the next day. The only change I would make would be to cut the lemon juice to 2 tablespoons as it overpowered the other flavors. Thanks for posting this wonderful tasty recipe.
