Ingredients
Black sanding sugar
1 lime wedge
Ice
1 tablespoon fresh lime juice
1 ounce light rum
3 tablespoons simple syrup
1/4 cup 100-percent pomegranate juice
1 ounce dark rum
Licorice spider, for garnish (optional; see Cook's Note below)
Preparation
Spread black sanding sugar on a saucer. Rub a lime wedge around the rim of a glass, then dip in sugar to coat. Add ice to glass.
Fill a cocktail shaker with ice, and add lime juice, light rum, simple syrup, and pomegranate juice. Shake 30 seconds. Strain into glass, leaving space at top. Gently pour in dark rum so it floats on top. Garnish with licorice spider tied to a stirrer.
