For the salsa, boil egg in boiling water for about 10 minutes until hard. Quench the egg, peel it and cut it into cubes. Roast the pine nuts in a pan without fat for about 4 minutes while turning, remove.
Wash, clean and dice the tomato. Onions clean, wash and cut into fine rings. Chop pine nuts. For the sauce whisk balsamic cream, salt and pepper. Add oil drop by drop.
Stir the sauce into the vegetables, pine nuts and egg. Meanwhile wash and peel the asparagus and cut off the woody ends. Bring salted water to a boil, season with sugar. Add asparagus to the water, bring to the boil and cook for 12-15 minutes.
Carefully remove the asparagus from the cooking water with a skimmer. Arrange asparagus and salsa on a plate.
