Chop the soft caramels. Bring 50 g cream and caramels to the boil, simmer while stirring until the caramels have melted. Coarsely chop the biscuits and stir into the cream caramel, except for a little bit for sprinkling. Line a box form (20 cm long; approx. 1 litre capacity) with cling film. Separate the egg, whisk the egg yolks and 25 g icing sugar until white-creamy.
Beat the egg white until stiff, while whisking in 1 tbsp. icing sugar. Whip 300 g cream until stiff. Mix egg yolk mixture and cream-caramel mixture. Fold in cream and beaten egg white one after the other. Pour the ice cream mixture into the box mould and freeze for at least 8 hours, preferably overnight. Defrost berries at room temperature, pass through a sieve and mix with 2 tablespoons of icing sugar. Remove the ice cream from the mould and cut into 12 slices. Cut the slices in half lengthwise.
