Soak the herring overnight; remove the milch and mash fine. Cut off the head, skin, and bone; chop the herring; add chopped apples, pickles, potatoes, olives, and capers. Put in the salad bowl; then add the yolk of a hard-boiled egg to the mashed milch, mustard, 1 teaspoonful of sugar mixed with 1/4 cup of vinegar, and a little lemon juice, salt, and pepper. Pour the sauce over the salad and garnish with olives and sliced lemon.
Hope you enjoy!
