In the meantime, drain the mandarins (save the juice), asparagus heads and mushrooms. Cut the asparagus into small pieces
Season the mayonnaise with sugar, pepper and a little tangerine juice and cucumber juice to make a delicious sauce. Oh yes, add some salt, but only a little.
Mix everything together and season to taste again. The salad should have a fruity, sweet and sour note.
Let the salad stand in the refrigerator for about 2 hours.
