In this festive tropical cocktail, rum is mixed with lime and passion fruit juices, then topped with vivid-blue curaçao.
In a cocktail glass, stir everything except the ice, blue curaçao and garnishes. Add crushed ice and mix with a swizzle stick or bar spoon, then pack more crushed ice on top. Pour the blue curaçao over the drink and garnish with orange and lime wheels.
To make simple syrup, simmer 1/2 cup water with 1/2 cup granulated sugar, stirring frequently until the sugar has dissolved. Let cool.
