vanilla cream orange popsicles

1 tbsp orange zest 
2 cups fresh orange juice
2 tbsp sugar
1 simple eggless vanilla ice cream:
1 vanilla bean
1½ cups whole milk
¼ cup unrefined granulated sugar
1 cup heavy cream
½ cup sweetened condensed milk
¼ tsp salt

1. First make the ice cream mixture: Split the vanilla bean lengthwise and heat it with the milk and sugar, stirring occasionally, to just below the boiling point. Allow to cool and chill. Remove the bean and scrape out the seeds, adding them to the milk. Add the cream, condensed milk, and salt and chill.
2. In a heavy saucepan, combine the orange zest, juice, and sugar. Bring to a boil over medium-high heat and cook until the orange juice has reduced to 1 cup. Remove from heat and cool. 
3. For layered pops, alternate layers of orange juice and vanilla ice cream, freezing each layer before adding the next.
