To start, whisk together the sour cream, horseradish, chopped dill, chopped parsley and lemon juice in a small bowl. Add the cucumber cubes and season with salt and pepper to taste.
Take your rye bread and spread a little Lurpak® on top, followed by the sour cream mix. Top with your smoked salmon, radishes and salmon roe, before adding a couple of the caperberries and dill sprigs to garnish. Serve each portion with a lime wedge before seasoning again with salt and pepper before serving.
