Boil eggs in boiling water for 9-10 minutes. Quench cold and let them cool down. Peel the eggs and cut into eighths. Meanwhile clean and wash the salad and radishes. Drain salad and pluck into bite-sized pieces.
Dab radishes dry and cut into slices. Stir the salad cream, yoghurt and vinegar until smooth. Season to taste with salt and cayenne pepper. Drain the prawns. Wash the dill, dab dry and pluck.
Put something aside for garnishing. Line a plate with some lettuce leaves. Mix eggs, remaining lettuce, radishes, crabs and remaining dill with lettuce cream and arrange on the lettuce leaves.
Garnish with dill.
