The Blue Lagoon is a popular summer cocktail known for its vibrant blue hue, made from vodka, blue curaçao, and lemonade. It was created by Andy MacElhone, the son of the famous Harry MacElhone of Harry's New York Bar in Paris. The drink's signature color comes from Blue Curaçao, a liqueur flavored with the dried peel of the Laraha citrus fruit grown on the island of Curaçao. While the fruit itself is too bitter to eat, the peels are rich in aromatic oils. The liqueur is naturally colorless but is dyed blue to evoke tropical imagery. The Blue Lagoon gained massive popularity in the 1960s and 70s as part of the 'disco drink' era, where visual appeal was just as important as flavor. It is typically garnished with a lemon slice and a maraschino cherry.
