Green Asparagus Soup

In this time of year lot's of people eat asparagus white or green. Especially the green ones are great for making a soup. I had some left-over ones from last night and decided to make a soup.

Ingredients:

Bunch of asparagus
Butter
Onion
Vegetable or herb stock (from cube)
Crème fraiche
Parsley


Preparation:
Wash the asparagus and cut the butts off.
Peel the bottoms of the asparagus, cut the points off and throw them away.
Cut the rest of the asparagus into fine pieces.
Peel the onion and cut it into small pieces.
Melt the butter in a pan and fry all the vegetables without cover.
Extinguish with water, add the vegetables or herbs broth.
Bring it to boil and then simmer for 30 minutes, no cover.
Mix the soup until it is smooth. Add some crème fraiche and mix a bit frothy.
Garnish the soup with parsley and if you have with a slice of smoked salmon.
Serve with a hard roll.
I have not added extra salt / pepper because the stock is salty enough.
