To make the Panna Cotta:

Cup of Yum
1. In a small bowl, sprinkle the gelatin over the water. Set aside as you prepare the remaining ingredients.
2. In a medium saucepan, whisk together the heavy cream, milk, and granulated sugar over medium heat.
3. Scrape in the seeds from the vanilla bean and add the pod.
4. Stir often until the sugar is dissolved and the mixture barely begins to bubble on the edges.
5. Remove from heat and set aside for 10 minutes (no longer). Discard the vanilla pod.
6. Add the gelatin with the water. Whisk until smooth.
7. Transfer among individual serving glasses about 3/4 full (leaving room in each one for the blood orange layer). Cover and chill until set, 4 hours to overnight.

To make the Blood Orange Gelatin:

1. In a small bowl, sprinkle the gelatin over the water. Set aside as you prepare the remaining ingredients.
2. In a small saucepan, whisk together the blood orange juice and sugar over medium heat.
3. Cook, stirring often, just until the sugar has dissolved and the mixture is barely starting to bubble around the edges. Remove from heat and stir in the gelatin with water.
4. Allow to cool for 10 minutes, then gently pour the blood orange juice over the chilled panna cotta.
5. Cover and return to the refrigerator for another 4 hours or up to three days until set.
6. Serve chilled.
