Prep Citrus & Berries: Rinse fresh cranberries under cold water in a colander and discard any soft berries. Grate 1 tablespoon of fresh orange zest and squeeze 1/2 cup of fresh juice.
Combine & Dissolve: In a medium non-reactive saucepan over medium heat, combine fresh orange juice, maple syrup, cane sugar, orange zest, cinnamon stick, and a pinch of salt. Whisk until sugar dissolves.
Simmer to Burst: Add the fresh cranberries. Bring to a boil over medium-high heat until berries start popping. Reduce heat to medium-low and simmer gently for 8 to 10 minutes, stirring occasionally and pressing some berries against the side of the pot to release juices.
Finish with Vanilla: Remove from heat. Discard the cinnamon stick. Stir in pure vanilla extract. The sauce will look slightly loose but thickens into a glossy glaze as it cools.
Chill & Serve: Cool to room temperature for 30 minutes, then cover and refrigerate for at least 2 hours before serving. Serve chilled or room temperature alongside holiday roast mains!
