Every island in the Caribbean has its own "special" drink, and here in St. Thomas, U.S. Virgin Islands, it is the "Bushwacker." Every bartender on island knows how to make them, and there are some variations, but this is the standard recipe. Tastes just like a chocolate milkshake...but be careful! It ain't no milkshake! Ever heard of a "virgin" drink? A "virgin" Bushwacker is a glass of ICE!! Haha! Multiply ingredients by the number of drinks you want. This recipe will make one drink.
