Pickled Herring Recipe: Nordic Tang With Onion and Dill

This Nordic pickled herring recipe delivers bold, briny-sweet flavors with minimal effort.

Traditional preparation involves a simple cure of salt and sugar, followed by a tangy vinegar marinade with sliced onions and fresh dill. The process transforms fresh herring into a delicacy that keeps well in the refrigerator for weeks.

What sets this dish apart is the balance of sweet, salty, and sour notes that develop during the marinating process. The herring becomes tender and fragrant, absorbing the aromatic flavors of the dill and onions.

Serve it chilled with rye bread or as part of a smorgasbord. This method preserves authenticity while keeping the technique accessible.

The herring quality is paramount. Source fresh, sushi-grade fillets from a reputable fishmonger or Whole Foods seafood counter. Look for firm, glossy flesh with a mild ocean scent—avoid any fishy aroma. For the salt cure, Diamond Crystal kosher salt dissolves cleanly and evenly, which is critical for proper curing. The vinegar should be a good white wine variety; Colavita or Lucini offer consistent acidity without harsh aftertastes.

No fresh dill? Dried dill at one-third the amount works in a pinch, though the flavor won’t be as vibrant. Short on allspice berries? A pinch of ground allspice can substitute, but whole berries infuse better. If white wine vinegar is unavailable, apple cider vinegar adds a fruitier note. The sugar can be reduced slightly, but don’t omit it entirely—it’s essential for balancing the brine’s sharpness.

This pickled herring improves with time. Store in a clean glass jar in the refrigerator for up to 3 weeks. The flavors deepen after 48 hours of marinating. For best results, turn the jar daily to redistribute the marinade. Always use a non-reactive container to prevent off-flavors.

Step-by-Step Instructions for Pickled Herring

This method ensures perfectly cured herring with balanced tang and aromatic depth.

Step 1: Cure the Herring Fillets

Begin by arranging the 1.5 lb Fresh Herring Fillets skin-side down in a single layer in a non-reactive dish. I recommend glass or ceramic to prevent any metallic reactions with the cure.

In a bowl, combine the 0.5 cup Kosher Salt and 0.25 cup Granulated Sugar until evenly mixed. Sprinkle half of this mixture over the fillets, then flip them and sprinkle with the remaining cure. This ratio creates the ideal balance of salinity and sweetness.

Cover the dish and refrigerate for 12-18 hours. The fillets should release liquid and become slightly firmer to the touch, indicating proper curing. Drain and rinse the fillets briefly under cold water to remove excess cure.

Step 2: Prepare the Pickling Brine

In a saucepan, combine the 1.5 cups White Wine Vinegar, 1 cup Water, 2 tsp Black Peppercorns, 2 pieces Bay Leaves, 1 tsp Mustard Seeds, and 6 pieces Allspice Berries.

Bring to a gentle simmer over medium heat until small bubbles form at the edges—this takes about 5 minutes. You’ll notice the spices begin to release their aromas into the liquid. Remove from heat and let the brine cool to room temperature before using.

This cooling step is crucial; adding hot brine to the fillets would partially cook them instead of preserving their delicate texture.

Step 3: Layer Fillets with Aromatics

Thinly slice the 1 whole Yellow Onion into crescents and coarsely chop the 0.5 cup Fresh Dill, stems included for maximum flavor. In a clean, non-reactive container, create alternating layers of herring fillets, onion slices, and fresh dill.

Add the 1 tbsp Lemon Zest evenly across the layers. The zest brightens the overall flavor profile and complements the briny tang. Pour the cooled brine over the fillets, ensuring they are fully submerged. Use a small plate or weight to keep the fillets under the liquid if needed.

Step 4: Refrigerate and Marinate

Seal the container and refrigerate for at least 24 hours before serving. This allows the flavors to fully develop and penetrate the fillets. I’ve found that 48 hours yields the best balance of tang and spice.

Check the fillets periodically to ensure they remain submerged in the brine. The pickling process is complete when the fillets take on a slightly translucent appearance and the brine has a pronounced aromatic quality. Serve chilled for the best texture and flavor.

Troubleshooting Perfect Results

Brine Too Harsh

If your brine tastes overly sharp after 24 hours, you likely used too much vinegar. Add 1-2 tbsp granulated sugar to the jar and stir gently. Let it sit for 6-8 hours before tasting again. The sugar will mellow the acidity without diluting the flavors. 💡

Herring Too Salty

Over-curing is a common mistake. If your fillets are too salty, soak them in cold water for 30-60 minutes to leach out excess salt. Change the water once if needed, then pat dry before returning to the marinade.

Fillets Not Submerged

If fillets float above the brine, they won’t pickle evenly. Use a small glass weight or a zip-top bag filled with water to keep everything submerged. Check daily and adjust as needed to prevent spoilage.

Cloudy Brine

Cloudiness often means the brine wasn’t fully cooled before adding to the fish. If this happens, strain the brine and bring it back to a simmer with fresh spices. Cool completely before pouring it over the herring to restore clarity.

Soft Texture

Herring can turn mushy if over-marinated. Stick to the 24-48 hour window for best texture. If they’re already soft, serve immediately—they’re still safe but best enjoyed fresh.

Weak Flavor

If the flavor seems bland, add 1 tsp lemon zest or an extra sprig of fresh dill to the jar. Shake gently and wait 12 hours for the new aromatics to infuse. 🌟
