I used two bunches of asparagus
Cut off the ends and discard.
Steam the remaining stalks until tender.
Put in an ice bath then purée with submersion blender.
In a separate pot;
Melt 2-3 tablespoon of butter over medium heat and then add 1 cup of whipping cream until it boils.
Then add puréed asparagus to cream mixture in pot and add salt and pepper to taste.
I add a few croutons for texture.
