Puree the frozen strawberries and sugar in a blender, slowly adding the cream and stirring occasionally. Put approx. 2 tablespoons of the ice cream mixture in the middle of a wafer, cover with another wafer and press slightly flat. Let the sandwiches freeze through for at least 5 hours, preferably overnight. Wash the lemon balm, dab dry and pluck off the leaves. Wrap the ice cream sandwiches in parchment paper and tie them up with gift ribbon. Dust the balm with icing sugar and decorate the ice cream with it
Waiting time approx. 5 hours
