Blue curaçao is a vibrant blue liqueur made from the dried peels of the Laraha orange, a fruit native to the island of Curacao. It has a sweet, slightly bitter flavor and is often used in cocktails to add color and a citrusy taste. The liqueur is typically around 25% alcohol by volume and can be enjoyed on its own or mixed in drinks like the Blue Lagoon or Blue Hawaiian. Its striking color makes it a popular choice for bartenders looking to create visually appealing beverages.
