Chop one pickled herring after removing the skin and bones, and add two cold boiled potatoes cut into small dice, a small sour apple peeled, cored, and chopped up small, a little cooked cauliflower, a handful of heart of celery finely shredded, and a few slices of pickled beetroot cut into thin strips. Season well with pepper and salt, oil, and vinegar, but mix carefully in the salad bowl in order that it may not have a messy appearance.
