750ML: On The Rocks Blue Hawaiian is a ready-to-drink cocktail that combines light rum, blue curaao liqueur, toasted coconut, and pineapple. The cocktail is inspired by the beaches of Honolulu, Hawaii and is described as having a tropical flavor that’s both refreshing and indulgent. Some say the drink has a smooth, mellow base from the rum, with bright citrus notes from the blue curaao, and a sweet, tropical profile from the coconut and pineapple.
