Ingredients

300 g (10 oz) marinated herring fillets (soaked to reduce saltiness, if needed)
2 medium-sized leeks (white and light green parts only)
1 medium apple (preferably sweet-tart, such as Granny Smith), grated
200 ml (¾ cup) sour cream
2 tbsp mayonnaise
1 tsp Dijon mustard
1 tbsp lemon juice
1 tsp sugar (optional, to balance flavors)
Salt and freshly ground black pepper, to taste
Fresh dill, chopped (for garnish)
Directions

Prepare the Ingredients:
Rinse the marinated herring fillets under cold water and pat them dry with a paper towel. Cut the fillets into bite-sized pieces.
Clean the leeks thoroughly, ensuring no dirt remains between the layers. Finely slice the leeks into thin rounds.

Make the Sauce:
In a medium bowl, combine the sour cream, mayonnaise, Dijon mustard, lemon juice, and sugar. Mix well until smooth and creamy. Adjust the seasoning with salt and pepper to taste.

Assemble the Dish:
Add the sliced leeks and grated apple to the sauce. Stir gently to ensure everything is evenly coated. Carefully fold in the herring pieces, being mindful not to break them apart.

Chill and Serve:
Cover the dish and let it rest in the refrigerator for at least 2 hours, allowing the flavors to meld together. Before serving, sprinkle with fresh dill for a pop of color and flavor.

Serving and Storage Tips

Serving: Serve the dish chilled as an appetizer or a side dish. It pairs wonderfully with fresh rye bread or boiled potatoes.
Storage: Store any leftovers in an airtight container in the refrigerator for up to 2 days. Avoid freezing as the texture of the cream-based sauce may change.
Variations

Spicier Twist: Add a finely chopped red chili or a pinch of cayenne pepper for a bit of heat.
Creamy Yogurt Version: Replace the sour cream with plain Greek yogurt for a lighter version.
Pickled Herring: Use pickled herring instead of marinated fillets for a more tangy flavor profile.
Vegetable Boost: Include finely chopped cucumbers or bell peppers for added crunch and color.
