Pour the golden rum, curacao, orgeat, lime juice and sugar syrup into a cocktail shaker with a handful of ice cubes. Shake until the outside of the shaker feels really cold.

Fill a tumbler with crushed ice then strain the cocktail over it. Slowly pour the dark rum over the top so it stains the top of the drink a rusty gold.

Garnish with fruit like pineapple, lime and cocktail cherries if you like.
