Break off the asparagus at the ends; it breaks where it is no longer woody. Cut into 2-3 cm long pieces and cook until al dente.
Halve the cherry tomatoes and pluck the Serrano ham into pieces.
Mix the dressing with olive oil, balsamic cream, salt, pepper, sugar and 2-3 tablespoons of the asparagus water. Add hot asparagus and stir. When the whole thing has cooled down a bit, add the halved tomatoes and ham and finally sprinkle with the chives and serve lukewarm.
