Herring in Mustard soured cream on Rye Bread

This pickled herring in mustard soured cream is a sophisticated take on a classic Nordic staple. The combination of tangy pickled fish with a rich, creamy dressing provides a wonderful balance of flavours, while the addition of fresh fennel and horseradish adds a crisp, peppery bite. It is a vibrant, textured dish that works beautifully as a light lunch or a stylish appetiser for a dinner party.

As a high-protein option, this recipe is as nourishing as it is delicious. Preparing the herring in advance is essential, as the overnight chilling allows the sharp mustard and citrus to mellow into the soured cream. Simply spoon the mixture onto triangles of toasted rye bread or dark seeded loaf for a simple, homemade snack that is packed with healthy fats and savoury appeal.
