Whip the cream until stiff, while pouring in 2 tablespoons of sugar. Mix the soured milk and grappa. Fold in cream
Wash the grapes, dab dry and, except for some for decoration, pluck them from the stalks. Remove the seeds from the grapes if necessary
Spread the grapes on 4 dessert bowls. Spread the grappa cream over them
Slice fine rolls off the chocolate with a peeler. Sprinkle over the cream. Moisten any remaining grapes with lemon juice and roll in 1 tbsp. sugar. Decorate the cream with sugar grapes and mint
You can replace the grappa with 2-3 tablespoons of freshly squeezed lemon juice. Instead of soured milk, the cream also tastes good with cream yoghurt or quark. Sweet seedless grapes are best suited for this dessert
