For those who love strawberries:
Rinse elderberries, drain and pluck from the twigs. Set aside two sprigs for garnish. Muddle the remaining elderberries with the sugar and pass through a sieve. Stir in Campari and pour into a shallow ice cube tray. Place in the freezer for 120 minutes, stirring frequently. Fill the sorbet into a piping bag, squirt into glasses and decorate with elderberry twigs and mint leaves.
Other : about 2 hours cooling time
