Wash the dill, shake dry and chop the flags finely. Chop pepper berries or crush them in a mortar. Mix dill, pepper, sea salt and brown sugar. Wash the salmon, dab dry and cut in half crosswise.
Spread 1/3 of the stain on a deep plate, place 1 piece of salmon with the skin side on top. Place 1/3 of the stain on top and place the other half of the salmon on top with the skin side facing upwards. Place the rest of the stain on top.
Wrap everything with foil. Chill salmon for 24-36 hours.
Clean the cabbage and cut it separately into very fine strips. Add 1/4 teaspoon of salt and 1/2 teaspoon of sugar to each cabbage and knead well with your hands. Let the cabbage stand for about 1 hour, kneading it occasionally.
Peel the shallot and cut into thin slices. Mix vinegar and mustard. Fold in the oil. Put cabbage in a sieve and drain. Mix half of the vinaigrette and both cabbages, season to taste with salt, pepper and a little honey.
Remove foil, take salmon out of the stain, rinse and pat dry. Cut approx. 200 g salmon from the skin into thin slices. Mix salad and shallots. Arrange 3 salmon slices, cabbage and salad.
Drizzle salad with remaining dressing and serve immediately. Wrap the remaining salmon in foil, keep cold and eat/use elsewhere.
