Heat milk and ½ cup water in a medium saucepan over medium-high heat until hot, but not boiling. Add rice and sugar. Reduce heat and simmer gently, stirring often, for 30-35 minutes or until rice is tender and consistency is thick and creamy. Remove from heat. Stir in vanilla.
Meanwhile, to make maple berries, combine berries and syrup in a medium frying pan over a medium heat. Bring to the boil. Gently boil for about 3 minutes or until berries are syrupy.
Serve rice topped with maple berries.
