Recipe for pickled herring in mustard sauceHomemade mustard herring with dill, red onion, and capers is wonderful on a piece of rye bread for Easter lunch or Christmas lunch. They are easy to make and they taste amazingly good.
Take the marinated herring fillets out of the brine and let them drip off on a piece of paper towel.
Finely chop half of the red onion. Chop capers and chop dill. Save the other half of the red onion and a little of the dill for garnish.
Mix sour cream with mayonnaise and the different kinds of mustard. Add chopped red onion, capers, and dill, and season with salt, pepper, and sugar.
Cut the drained pickled herring fillets into smaller pieces of about 2 cm. Turn the herring pieces in the dressing, and garnish with red onions in thin slices and dill.
