1Pour the heavy cream and milk into a saucepan.
Add the sugar and split the vanilla bean lengthwise, scraping out the seeds.
Add the vanilla seeds and the pod to the saucepan.
Heat the mixture over medium heat, stirring occasionally, until the sugar is dissolved and the mixture is hot but not boiling.
Remove the saucepan from the heat and let it sit for about 10 minutes to infuse the vanilla flavor.
Remove the vanilla pod from the mixture.
Pour the mixture into serving glasses or molds.
Refrigerate for at least 4 hours or until set.
Serve chilled, optionally garnished with fresh berries or a drizzle of caramel sauce.
