Method
In a mixing glass, add 2 oz Angostura Grand Reserve Rum, ½ oz Apple Crisp Syrup, and 2–3 dashes Angostura aromatic bitters.
Stir with a bar spoon until chilled.
Strain into a glass with large clear ice cube.
Garnish with an apple fan and cinnamon stick or star anise.
Apple Crisp Syrup
Combine the chopped apple, apple cider, brown sugar, and cinnamon sticks in a small saucepan over medium heat.
Bring to a low simmer, stirring until the sugar completely dissolves.
Reduce heat to low and cook for 15–20 minutes until the apples are soft and the liquid turns syrupy.
Remove from heat, stir in 2–3 dashes of Angostura orange bitters, and let cool.
Strain out the solids using a fine-mesh strainer into a clean jar. Replicate or store sealed in the refrigerator.
