I made this during the blizzard--so I had to substitute fresh spinach for the romaine, and a touch of cream for the milk. I also added garlic. Instead of letting it stand in the blender, I kept it hot and pureed with an immersion blender (less to wash--and too cold for anything but hot soup) Because I was having hot, I tempered in the sour cream. The result--a lovely soup with a fresh clean taste. I will make this again. If summer ever comes, I can envision serving this as a cold soup.
Delicious, great in the summer.
Incredibly easy to make tastes delicious. Perfect for when you want something healthy but don't have much time.
