A Bahamian drink, there is no official recipe, but in a nutshell is coconut water + alcohol. Usually mixed with Gin.
In recent years, a popular mix has included, coconut water, gin, condensed milk (cream) and sweet milk, and sometimes coconut flavored rum.
Likely received its name because coconuts grow on very tall trees -> the juice coming from the sky.
