My family loved this soup, but I did make several flavor enhancing changes to the recipe: 1. I used 8 cups rather than 6 cups of broth 2. I used 6 cloves of garlic 3. 1 Tablespoon of oregano 4. instead of onion I used 1 large shallot I let is sit overnight in the fridge before I served it, allowing the flavors to meld.
I love the bright flavor of the fennel in this soup.
