Place 4 tomatoes in a blender, and then add 4 radishes, 1 cucumber, 1 bell pepper, the fennel, scallions, parsley, and lemon juice. Puree until very smooth, about 1 minute.
Line a large bowl with 3 layers of cheesecloth. Pour puree into the bowl, gather cheesecloth around puree, and tie into a bundle. Tie ends to a long wooden spoon, and balance spoon on the rim of a deep pot, suspending bundle in the pot. Refrigerate and strain for 2 hours to extract a clear broth.
Gently squeeze solids in cheesecloth to extract liquid. (You should have 4 cups liquid.) Discard solids.
Season broth with salt and cayenne pepper. Garnish with remaining tomato, radish, cucumber, bell pepper, and parsley. Drizzle with oil and vinegar, and serve cold.
The broth from this soup can be served as a cold beverage instead of soup.
This sounded very interesting. I made it yesterday. Could not find any fennel at the grocery store, and all of the fresh veggies were very expensive, but I gave it a try anyway. Tasted very good - needed a little more salt. One problem is that the recipe did not end up with 4 cups of liquid. Probably summer vegetables will work better; maybe adding the salt at the beginning of the process would help to extract more liquid. Will try again.
