The Rum Old Fashioned is an innovative take on the traditional Old Fashioned cocktail, challenging the notion that whiskey is the only spirit suitable for this timeless drink. While some purists may scoff at the idea of using rum, it’s essential to recognize that the Old Fashioned is more of a template than a strict recipe.

Crafting the Perfect Rum Old FashionedThere are countless ways to create a Rum Old Fashioned, varying by the choice of rum, sweeteners, and bitters. This particular version features:
- 2 ounces dark rum: Aged in barrels, dark rum brings rich oaky notes that will appeal to whiskey lovers.
- 1 teaspoon allspice dram: This spiced liqueur adds a layer of complexity and warmth to the cocktail.
- 1 teaspoon demerara syrup: Made from raw cane sugar, this syrup offers a deeper flavor and richer mouthfeel compared to simple syrup.
- 2 dashes Angostura bitters: These bitters provide bold aromatic notes and structure.
- 2 dashes orange bitters: Enhancing the cocktail with a zesty citrus element, orange bitters complement the richness of the rum.
- Prepare Your Glass: Start by placing a large ice cube into an Old Fashioned glass. The large cube will chill your drink while minimizing dilution.
