Marinade: Mix ingredients in detail.
Trout: Coat with the marinade. Cover with plastic wrap and refrigerate for 4-5 hours.
Dressing: Boil half of the lemon juice with the sugar.
Bind lightly with cornstarch and cool. Fold in remaining juice of one lemon and olive and sunflower oil or other vegetable oil, one at a time, and season with soy sauce. If the sauce is too viscous, dilute with a small amount of hot water and whisk.
Trout: Stripe off marinade, rub dry with paper towels and cut into paper-thin slices.
Dressing:
Arrange the salmon trout slices in a circle in the center of the plate and drizzle with lemon dressing. Garnish with coriander leaves, sprinkle with dill and add 2 half quail eggs.
