Boil eggs for 9 minutes, rinse with cold water and peel. Wash the fish, cut in half lengthwise, remove the middle bones and skin. Cut the fish fillet diagonally into approx. 5 cm wide pieces. Season the fish pieces with pepper and chill briefly. For the sauce, boil up the cream with horseradish, season with salt, sugar and lemon juice. Wash the parsley and put something aside for garnishing. Pluck the remaining leaves from the stems and chop them.
Chop the eggs. Season fish pieces with salt, turn them in flour, knock off excess flour. Fry the fish pieces in portions in hot oil for 4-5 minutes on each side until golden brown. Add parsley and eggs to the sauce. Arrange the fish pieces with some sauce on a plate and garnish with the remaining parsley. Remaining sauce extra is enough. Boiled potatoes taste good with it
