Hurricane

1 part light rum (Brugal)
1 part dark rum (Zacapa)
1/2 part lime juice
1/2 part passionfruit juice (or one-to-one mix of OJ and grenadine)

This Bourbon Street staple clocks in on the sweeter side, which makes for a solid cold pour on a hot day. Add pineapple chunks and a cherry for extra effect at any rooftop party.
