Tarragon Chicken and Rice Soup

http://allrecipes.com/recipe/231509/tarragon-chicken-and-rice-soup

I used 2 quarts broth. It was quite a thick soup after it sat for a few minutes cooling. Could have used even more broth. This would have been fine with half the rice too. I cooked an entire cauliflower in the broth first and pureed it so the soup would be more creamy.
