Chop the peeled shrimp and let them dry on kitchen paper or leave in a sift for 10 minutes.
Mix mayonnaise, grated horseradish, dill (save some dill for garnish) and salt and pepper.
Add the chopped shrimp to the creamy mixture.
Fry the bread in butter.
Serve the shrimp mixture on top of the fried bread and top with caviar for a true elegant nordic taste, garnish with a sprig of dill and a lemon wedge on the side.
