Herring Salad with Sour Cream Sauce

This is Heringssalat, the kind of dish you’ll find on every Northern German table during holidays and celebrations. Marinated herring fillets get layered with crisp tart apples, thinly sliced onions, and a tangy sour cream sauce, then marinate in the fridge for hours until every bite is creamy, briny, and bright.

The apple is the genius ingredient. Its tartness cuts through the rich sour cream and salty herring, adding a crisp, fruity contrast that keeps this salad from feeling heavy. Use a firm tart apple like Granny Smith so it holds its shape during the long marinate.

Five hours in the fridge isn’t just chilling time. The flavors meld, the onion softens and sweetens, and the sauce absorbs some of the herring’s brine to create a unified dressing.

Kitchen Tips

• Use good-quality marinated herring fillets (Matjes style or in wine marinade). The herring’s existing flavor is the foundation of the whole salad.
• Slice the onions as thin as possible. Thick rings stay sharp and overpowering even after five hours of marinating.
• The lemon juice and sugar in the sauce aren’t optional. Lemon brightens the sour cream and sugar rounds out the acidity so nothing tastes flat.
• Fresh dill sprinkled on just before serving adds color and a clean, herbal lift.

Variations

• Add diced cooked beets for a Russian-style herring salad with gorgeous pink color.
• Fold in diced pickled cucumbers for extra crunch and brine.
• Serve on dark rye bread as open-faced sandwiches for a traditional Scandinavian presentation.
