Peel the asparagus, cut into pieces and cook in salted water until soft, it should be firm to the bite. Then drain and let cool.
Slice the eggs and cut the ham into strips. Finely chop the onion and mix the cream, some mustard, a pinch of nutmeg and white pepper into a dressing. Put the drained asparagus in a bowl and fold in the dressing, ham and egg slices. Then sprinkle with chives.
