Which mixer is used in a Blue Lagoon cocktail?

The Blue Lagoon cocktail is known for its vibrant blue color, which primarily comes from blue curaçao, a liqueur made from the dried peels of the laraha citrus fruit. The mixer that complements the blue curaçao in a Blue Lagoon is typically a clear, lemon-lime soda such as Sprite. This mixer adds sweetness and a refreshing citrus flavor that balances the boldness of the blue curaçao, making the cocktail not only visually appealing but also enjoyable to drink.

Other mixers like ginger ale, cranberry juice, or pineapple juice do not align with the traditional recipe and flavor profile of the Blue Lagoon. Ginger ale tends to have a spicier flavor that would conflict with the citrus notes, while cranberry juice would add a reddish tint that detracts from the cocktail's signature blue hue. Pineapple juice, although sweet, would also alter the intended flavor structure. Thus, Sprite is the correct mixer for achieving the authentic taste and appearance of a Blue Lagoon cocktail.
