Start by boiling your eggs. Place the eggs in a pot, cover them with water, and bring it to a boil. Once boiling, reduce the heat and let the eggs simmer for about 10-12 minutes. Afterward, transfer them to an ice bath to cool before peeling.
In a mixing bowl, combine the cooked prawns with 4 tablespoons of mayonnaise. Squeeze the juice of one lemon over the mixture, adding a touch of zest. Gently fold everything together until the prawns are coated evenly.
While the prawn mixture is resting, slice the boiled eggs into rounds. Also, prepare your cucumbers by cutting them into thin slices.
On a serving plate, lay out the slices of rye bread. Start layering with lettuce leaves, followed by the prawn mixture. Carefully place the sliced eggs on top, and then add the cucumber slices. For a final touch, garnish with fresh dill and lemon slices.
