1. Using a vegetable peeler or a small, sharp knife, carefully cut 4 strips of zest (remove any white pith) from the orange, then juice the orange (yield 75-100ml – reserve 1tbsp for the garnish).
2. Pour the California Prune juice, spiced rum and fresh orange juice into a small saucepan, and then add the cinnamon stick and two strips of the orange zest.
3. Warm over medium-low heat (slight simmer) for 5 minutes.
4. While the cocktails are warming, prepare the sugar plums by rolling two California Prunes in the remaining 1 tbsp orange juice (or water will work) and set on a plate, sprinkle with sugar to coat, and allow to dry for 30 seconds, then sprinkle with sugar again.
5. Divide the cocktail between two glasses. Garnish each glass with a piece of orange zest, a sugar plum on a cocktail pick, and a cinnamon stick.

Serving Suggestion: Pair with Spiced Prune Snack Cake for an extra cozy evening!
