A quick and easy Danish open-faced sandwich featuring tangy pickled herring, creamy dill butter, and hearty rye bread. Perfect for entertaining or a comforting snack with Scandinavian charm.
Use a serrated knife to slice rye bread thinly without squishing it. Softened butter should be spreadable but firm to avoid sogginess. If pickled herring is too salty, rinse briefly under cold water. Assemble just before serving to keep bread from becoming soggy. Dill butter can be made a day ahead to enhance flavor. For gluten-free, substitute rye bread with gluten-free rye-style bread or crispbread. Vegetarian versions can use marinated grilled mushrooms or smoked tofu instead of herring.
