01 - In a small saucepan, combine water, cinnamon stick, cloves, star anise, and ginger slices. Bring to a gentle simmer over medium heat.
02 - Allow the mixture to simmer for 5 minutes to fully infuse the water with the spice flavors.
03 - Remove the saucepan from the heat. Strain the spiced water through a fine-mesh strainer into a heatproof pitcher or measuring cup. Stir in the fresh blood orange juice, honey (or maple syrup), and vanilla extract until the sweetener is completely dissolved.
04 - Divide the whiskey evenly between two heatproof mugs. Carefully pour the warm, spiced blood orange mixture over the whiskey in each mug. Stir gently to combine.
05 - Garnish each mug with a slice of blood orange. An additional cinnamon stick can be added for aroma, if desired. Serve immediately.
