I added basil leaves and garlic to the soup. I thought the directions were a bit unclear, too.
I cooked my apples, celery, and onion in pineapple juice to make it more of a sweet soup. Then I creamed it with vanilla soy milk and a little maple syrup, it was heavenly. I'm going to try this with veggie stock and cream next time I need a savory soup.\
This recipe has potential, but it needs an absurd amount of salt to get some flavor out of it, as well as some cream to thicken it up a bit. Six cups of water dumped on a bunch of fruit and vegetables just isn't enough. The recipe ends up tasting as plain as it looks if you don't add some finishing touches.
I added extra salt and pepper to taste and thought it was decent. In the future I would serve it with some creme fraiche.
