Mix cheese and crème fraîche. Wash the herbs and, except for some dill, chop finely. Cut the cream in half. Mix half with herbs, the rest with horseradish. Season to taste
Line the box form (22 cm long; approx. 1.25 l capacity) with foil. Spread a thin layer of horseradish cream on one side of each bread, smooth out half of the remaining cream in the tin. Cover with 3-4 slices of salmon, slightly overlapping. Place 2 slices of bread on top with the cream side down. Then spread 1/2 herb cream on the bread layer. Cover with 3-4 slices of salmon, slightly overlapping
The rest of the bread, salmon (except for 3-4 slices) and the rest of the creams alternately layer in the same way, finishing with salmon. Cover with foil. Cool for at least 1 hour. Turn over, remove foil. Cover with the rest of the salmon, garnish
