1. In a large stainless-steel saucepan, combine berries and sugar. Add cinnamon stick, salt, nutmeg, and orange juice. Using a paring knife, scrape vanilla seeds into mixture; add pod. Set pan over medium-high heat, and bring to a boil. Cook 1 minute.

2. Remove pan from heat; pour mixture into a sieve over a medium bowl. Transfer solids to another medium bowl; set aside. Return liquid to the saucepan; bring to a boil.

3. In a small bowl, combine cornstarch and 1/4 cup water. Add to boiling liquid. Cook, whisking constantly, until mixture coats the back of a wooden spoon, about 1 minute.

4. Remove pan from heat, and pour mixture over reserved solids. Remove and discard cinnamon stick and vanilla pod; serve warm.
