Mix the yolks of the boiled eggs with 1 teaspoon each of mustard and lemon juice until smooth, ideally with a magic wand in a tall blender or directly in a tall glass with a twist-off lid. Pour in about 125 ml of oil in a thin stream, stirring constantly, until it looks like mayonnaise. Mix with salt and pepper from the mill, 2 tablespoons of vinegar, the finely chopped herbs and the medium-coarsely chopped egg white.
Leftovers - which are unlikely - can be stored in the twist-off jar 2-3 in the refrigerator.
It goes even faster with ready-made mayonnaise, but does not have the advantage of being able to use Easter eggs.
