Fill a shaker with ice cubes.

Pour in the rum, Galliano, lime juice and orange juice into the shaker and shake vigorously until well combined.

Strain the mixture into an old fashioned glass over fresh ice cubes or crushed ice if available.

Add a splash (about 1 teaspoon) of grenadine syrup to the top for color and sweetness and give it a gentle stir to combine all ingredients together before serving!
