Peel and bone the fish and pluck it into pieces that are not too small. Cut the celery, Edam and apples into small strips. Chop the onion. Mix all salad ingredients together.
Prepare a strong marinade from vinegar, oil, spices and chives, pour over the prepared ingredients and refrigerate for approx. 20 - 30 minutes.
This goes well with rolls or white bread and, of course, a fresh jever.
