Cook the two types of asparagus separately in a little salted water or over steam until not too soft (green asparagus: eight to ten minutes, white asparagus: twelve to fifteen minutes).
In the meantime, beat the juice of one lemon, sour milk, mustard or sour cream, soup, oil, salt and pepper with a hand mixer or possibly in a hand blender to a foamy sauce.
Pluck the chervil leaves from the stems.
Cut the asparagus in half lengthwise while still warm and arrange decoratively on plates. Pour the sauce over them and garnish generously with the chervil leaves.
Tip: If you like, you can enrich the asparagus salad with raw ham or possibly Bündnerfleisch. Of course, it can also be prepared with only one type of asparagus.
