A simple and elegant Danish open-face sandwich featuring dense rye bread topped with pickled herring, fresh dill, radishes, and a tangy mustard dressing. Perfect for quick lunches or casual entertaining.
Use dense rye bread to prevent sogginess. Spread butter thinly to create a moisture barrier. Drizzle mustard dressing last to keep bread crisp. Soak onions to mellow sharpness. For vegan or gluten-free adaptations, substitute bread and toppings accordingly.
