Wash the asparagus and drain well. Peel only the lower third of the green asparagus and cut off the ends. Bundle the asparagus as desired and cook in boiling salted water for 7-10 minutes.
In the meantime, mix vinegar, mustard, sugar, a little salt and pepper. Finally, beat both types of oil into the mixture. Drain the asparagus well and pour the vinaigrette over it. Sprinkle with pink berries and chervil leaves and garnish as desired.
Serve lukewarm or cold.
