Rum Old-Fashioned
A delightful Caribbean twist on the timeless classic. This recipe swaps whiskey for crisp light rum, sweetened with powdered sugar and aromatic bitters. The experience is elevated with a fiery float of 151 proof rum and the zest of fresh lime, creating a complex and refreshing sipping cocktail.
What it tastes like
The aroma is dominated by lime oils and the sharp heat of the overproof rum float. On the palate, the sugar softens the bite of the light rum while the bitters provide a dry, herbaceous counterpoint. The mouthfeel is medium-bodied with a slight grain from the powdered sugar. The finish is warm and clean with a brief citrus note.
