This is a great soup, although I felt it was missing something. I added some oregano and brown sugar and that helped it out (a bit unconservative, but I was feeling adventurous). It was very good, but I think I'll stick to my usual recipe.
Wonderful soup. I used a scant 4 cups of onions and the white wine. It has a rich flavor without being over strong in anything. and the cheese looks wonderful with a nice touch of brown on it. It's company worthy and everyday easy to make and creates the most wonderful aroma. I had people following their noses into the kitchen wanting a sample. It's a keeper.
