Ive made a similar recipe a few times and it was a big hit in our house. The difference is, I added a couple of canned plum tomatoes, a few shakes of smoked tabasco and a little white and black pepper. I chilled the soup in the fridge and put the serving bowl in the freezer overnight. It was really,reallly good.

Lea,
I made this today and it was light and fluffy. I used a whisk and then a wooden spoon,not a mixer where usually I would use my KitchenAid. Is it possible you overmixed?
