Place all ingredients in the Cook Expert bowl and set for 6 minutes, speed 4, temperature 80C.

Set aside to cool for 1 hour.

(If using the stove top, place all ingredients in a medium saucepan and combine well with a whisk. Stir constantly over a medium heat until the custard thickens slightly - just enough to coat the back of a wooden spoon.)

Pour the cooled custard into the frozen bowl of an ice cream machine and churn until it is the consistency of soft-serve ice cream. (Add the chopped candied orange peel, if using, just for the last minute or two.)

Place into a container, seal with a lid and put in the freezer until completely frozen.
