French Onion Soup

We've gotten tons of organic red & yellow onions from the farm the past couple of weeks. What else could I make but french onion soup! I used this recipe as a base and modified it quite a bit. I sauteed the onions with a little sugar (a Julia Childs tip) for over an hour until they were caramelized and a dark golden brown. Added fresh sage, used homemade chicken stock instead of beef broth (and used a lot more liquid), and finished it off with 1/4 cup sherry. Tres magnifique!
