Remove the waffle bases from the chocolate kisses, mash the foam mass with a fork and mix with the orange peel. Whip the whipped cream until stiff and fold into the chocolate mixture.
Pour the mixture into a flat form, cover with cling film and freeze for approx. 2 hours. Stir it 2-3 times with a spoon.
Shape 4 balls out of the ice cream mass, place in 2 ice cream cups and pour 2 tablespoons of egg liqueur over each. Decorate each with a chocolate waffle.
