Fresh orange slices and cherries, for garnish (optional)
Instructions
Make the Ginger Syrup
Place the sugar, water and sliced ginger into a medium saucepan over medium heat. Bring to a boil, then reduce heat to low. Simmer until thick and syrupy, then removing ginger slices. Set aside to cool.
Mix together the gin, vermouth, campari, cooled ginger syrup and orange juice in a freezer-safe container.
Freeze for 2 hours, then remove and stir. Place back in the freezer for another 2-3 hours until slushy.
Divide into 4 small glasses and garnish with orange and cherries, if using.
