1Coarsely crush half of the candy canes and put them in a medium heavy-based saucepan. Add the sweetened condensed milk. Stir over medium-low heat, until the candy dissolves.
2Pour the cream into a small saucepan. Stir over medium heat for 3-4 minutes until warm. Add to the candy mixture and stir over medium heat until mixture is smooth. Stir in the salt. Transfer to a heatproof container. Allow to cool.
3Cover and refrigerate for 2 hours until cold.
4Pour the chilled mixture into the ice cream bowl. Set the ice cream maker to the desired setting and churn.
5Coarsely crush the remaining candy canes. Add the candy canes once the machine specifies to add in Mix-Ins.
6Once the ice cream is frozen transfer to a freezer-safe container, just large enough to contain the ice cream. Freeze for 6 hours or overnight for firmer ice cream.
7Scoop and serve in bowls sprinkled with extra crushed peppermint candy canes.
8Store ice cream in the freezer for up to 2 weeks. The ice cream will become very firm after freezing overnight, so remove from the freezer and stand at room temperature for 5-10 minutes before serving for easier scooping.
