Crush 1 teaspoon of capers and trout fillets in a universal shredder. Mix sour cream, remaining capers and trout puree. Whip cream until stiff and fold in. Season cream with a little lemon juice, salt and pepper and chill. Wash the herbs and dab dry.
Pluck the thyme and marjoram leaves from the stalk. Put milk, egg, herbs, flour and a little salt into a tall mixing bowl and puree with a hand blender. Let the dough rest for about 15 minutes. Heat 1/2 teaspoon of oil in a coated pan. Put 1/4 of the dough into the pan and fry it to a thin pancake, turning once. Fry 3 more pancakes in the same way and let them cool down. Spread the trout cream on the 4 pancakes and roll them up. Freeze the pancakes for about 20 minutes (so that you can cut them better). Wash the tomatoes, grate them dry, clean them and cut them into thin slices. Wash and clean spring onions and cut them into thin rings.
