Boil the eggs hard for about 10 minutes. Quench, peel and let them cool down. Halve the eggs, remove the yolk and place in a bowl. Crush them finely with a fork. Stir with mayonnaise, cream cheese and beetroot juice until smooth. Season with salt, pepper and 1 pinch of sugar.
Spread the cream with a teaspoon into the egg halves. Cut the trout fillet and salmon into small pieces. Cover eggs with trout, salmon or caviar. Garnish as desired with dill and lime.
