Prep the orange peel: Use a peeler to remove wide strips of zest.
Avoid the bitter white pith. You’ll need about 4–6 strips.
Lightly crack the spices: Gently tap the cinnamon sticks and whole nutmeg with the back of a knife to expose more surface area. Don’t pulverize them—just a light crack is enough.
Combine in a jar: Add cracked nutmeg, cinnamon sticks, cloves, orange peel, vanilla bean (split), and peppercorns if using to a clean glass jar.
Add the rum: Pour the entire bottle over the spices.
Seal the jar and give it a few gentle swirls.
Infuse: Let it steep at room temperature for 24–72 hours. Swirl once or twice a day. Start tasting at the 24-hour mark.
When the nutmeg and spice are bold but balanced, it’s ready.
Sweeten (optional): Dissolve 2–4 tablespoons brown or demerara sugar in 2 tablespoons hot water to make a quick syrup. Stir into the infused rum to taste.
Strain: Pour through a fine-mesh strainer lined with cheesecloth or a coffee filter into a clean bottle. This removes sediment and keeps the flavors clean.
Rest briefly: Let the strained rum sit for at least a few hours before serving.
The flavors round out and soften.
Serve: Enjoy neat, over ice with an orange twist, or mix into cocktails.
