Step-by-Step Instructions
Step 1: Soak the herring (only if using salted fillets)
If you’re starting with salted herring fillets (not already pickled), place them in a bowl and cover with 720 ml cold water. Soak for 45 minutes, changing the water once halfway through (at the 20–25 minute mark). This removes excess salt so the final pickles taste balanced, not briny.
Drain thoroughly and pat the fillets dry with paper towels.
Step 2: Make the sweet-spice brine for the rollmops
In a small saucepan, combine 240 ml distilled white vinegar, 240 ml water, 100 g sugar, 6 g kosher salt, 1 tsp allspice berries, 1 tsp peppercorns, and 2 bay leaves.
Set over medium heat and bring to a gentle simmer (about 190°F / 88°C). Simmer for 2 minutes, stirring to fully dissolve the sugar and salt.
Remove from heat and cool the brine to room temperature (20–22°C / 68–72°F), about 30 minutes. Do not pour hot brine over the fish; it will change the texture.
Step 3: Assemble the rollmops (rolled pickled herrings)
Lay a herring fillet flat on a cutting board. Place a few strands of yellow onion near the wider end and add 1 dill pickle spear. Roll the fillet up snugly (like a jelly roll) and secure with a toothpick.
Repeat with the remaining fillets to make 12 rollmops.
Step 4: Jar and marinate the rollmops
Pack the rollmops into a clean 1-liter glass jar (or two smaller jars). Tuck in 15 g fresh dill and any remaining onion slices.
Pour the cooled brine over everything, making sure the rollmops are fully submerged. If needed, gently press them down with a clean spoon.
Cover and refrigerate for 24 hours before serving (they’ll taste even better at 48 hours).
Step 5: Quick-pickle the red onions
Add 120 ml apple cider vinegar, 120 ml water, 25 g sugar, and 6 g salt to a small saucepan. Bring to a simmer over medium heat (about 190°F / 88°C) and simmer for 1 minute, just until the sugar dissolves.
Place the sliced large red onion in a heatproof jar or bowl. Pour the hot pickling liquid over the onions. Cool at room temperature for 30 minutes, then refrigerate until serving.
Step 6: Mix the creamy curried herring and chill
In a bowl, whisk together 250 g sour cream, 60 g mayonnaise, 2 tsp curry powder, 8 g sugar, 15 ml lemon juice, and optional 1/2 tsp Dijon mustard. Taste and adjust: add a pinch more sugar for roundness or a few drops more lemon for brightness.
Fold in the diced apple, finely diced red onion, and 10 g chopped dill. Gently stir in the 350 g drained pickled herring.
Cover and refrigerate for 1 hour so the flavors bloom and the sauce thickens slightly.
Step 7: Assemble the platter and serve
On a large serving board or platter, arrange:
Rye bread (fan out 12 slices), a small bowl of extra sour cream, a mound of quick-pickled onions, the jar (or a dish) of rollmops, and a bowl of curried herring.
Garnish with extra fresh dill and (optional) lemon wedges. Serve cold, straight from the fridge—this is when herring tastes its best and cleanest.
Pro Tips
- Cool the brine completely before pouring it over herring. Warm brine can toughen the fish and mute the bright vinegar flavor.
- Choose the right herring: salted fillets give you the most “from-scratch” rollmops. For curried herring, jarred pickled herring in brine is easiest and very traditional.
- Keep everything submerged in the rollmops jar for even pickling. If needed, use a small clean ramekin or fermentation weight to hold them down.
- Dice the apple small (about 5 mm). It should add crunch without overpowering the tender fish.
- Serve extra rye and onions. People tend to build second and third open-faced bites.
Variations
- Mustard-dill herring: Swap the curry sauce for a mustard sauce: whisk 2 tbsp whole-grain mustard + 1 tbsp Dijon into the sour cream mixture, and add 1 tsp honey instead of sugar.
- Beet-pink pickled onions: Add 60 ml beet juice (from cooked beets or bottled) to the onion pickling liquid for a vivid magenta color and slightly earthy sweetness.
- Spicier rollmops: Add 1/2 tsp red pepper flakes to the rollmops brine and include a few thin slices of fresh chili in the jar.
Storage & Make-Ahead
Rollmops: Keep refrigerated in their brine at ≤ 40°F / 4°C. Best after 24–48 hours. They keep well for 7 days (flavor intensifies over time). Always use a clean utensil to remove pieces.
Curried herring: Refrigerate in an airtight container and eat within 3 days. The apple will soften slightly as it sits.
Quick-pickled onions: Refrigerate up to 14 days. They’re great on sandwiches beyond this platter.
Make-ahead plan: Make rollmops 1–3 days ahead. Pickle onions and mix curried herring the day before (or at least 1 hour before serving).
