Cut the herrings into strips as for fork bites, the remaining roast and the apples into thin slices. Halve and slice the boiled eggs and cucumber, cut the potatoes as you would for potato salad. Mix everything together and season with oil, a grated onion, chopped capers, mustard, vinegar, salt, pepper and plenty of chopped parsley.
Dice the bacon, leave it out, add it to the salad while it is hot, mix again and let it steep.
With us, the salad usually lasts for 2 days and is served with a slice of black bread with butter and a cold Freiberger Pilsner.
