Form 4 rings (approx. 4 cm high and 6 cm Ø) from 4 strips of aluminium foil and place them in round dessert bowls. Finely crumble the lady fingers and, except for 1 tablespoon, distribute them into the rings.
Select the blueberries, wash if necessary and drain well. Mix cream cheese, sugar and lime juice. Whip cream until stiff. Fold in cream and berries, except for 1 tbsp. Spread the cream into the rings and smooth it down.
Sprinkle each with 1 tablespoon of juice and chill for about 2 hours.
Carefully loosen the aluminium rings. Decorate the cream with the remaining blueberries and sprinkle with remaining crumbs.
