Add cheese and stir until smooth. Add cooked fish, raw shrimp, smoked fish, finely chopped dill, lemon zest and lemon juice. Season.
Transfer mixture to a large ramekin. Top with mashed potatoes and dot with remaining butter. Bake for 45 mins, or until heated through and mashed potatoes are golden. Serve topped with extra dill sprigs.
