This flavorful soup is known as "Spargelsuppe" in Germany, where it is very famous. The Germans tend to prefer white asparagus to green (unlike many people in the United States) and this mouthwatering soup is a luxurious treat. The pureed asparagus and broth mixture also contains cream for a decadent touch. The asparagus tips are reserved until the last few minutes or cooking time. They are the tastiest part of the asparagus and they add a wonderful luxury to the broth.
