Leilani Volcano
The drink was originally served in the 1970s at Walt Disney World's Polynesian Resort, but don't let that dissuade you from trying it—this isn't kid stuff when made with the right coconut rum. Leilani means "heavenly lei" or "royal child" in Hawaiian; the volcano refers to the bowl in which the original drink was served. Nowadays you're more likely to find it served in a tiki mug or Zombie glass, however.
Works great as a pre-made punch for parties, too.
3 oz guava nectar
1.5 oz pineapple juice
.75 oz fresh lime juice
.25 oz simple syrup
2.5 oz coconut rum (Bacardi Coconut Rum or Koloa Kauai Coconut rum)
Shake well with ice cubes. Pour unstrained into the vessel of your choice. Garnish with a cherry speared to an orange slice. If you find this too tame, you can use 1.5 oz coconut rum and one ounce white rum to increase the octane.
