For the salad, clean and wash the broccoli, drain well and grate with a square grater. (You can use the whole broccoli or just the florets. Use the stems for soups).
Peel the onion and cut into fine strips. Put the apple cider vinegar in a small bowl. Let the onion strips steep in vinegar for 15-20 minutes. (Afterwards you could use the vinegar additionally for mayo, if you want it to be a bit more sour, or for other salads). Soak the goji berries in lukewarm water for about 10 minutes.
Roughly chop the almonds. Lightly drain onion strips and goji berries. Mix together with broccoli and chopped almonds in a bowl.
For the mayonnaise, peel and finely chop the ginger. Whisk the egg yolks with an egg whisk in a bowl. Add as much sesame or macadamia oil in a very thin stream, stirring constantly, until a thick-creamy mayo is obtained.
Stir cider vinegar and remaining oil also in a thin stream under the mayo. Stir in honey. Fold in ginger and poppy seeds. Season to taste with salt. Mix the ginger-poppy seed mayo well with the salad. Buckwheat noodles or baked salmon taste really great with it.
