Angelo Azzurro, translated as a blue angel, is an Italian cocktail that combines gin, triple sec (Cointreau), and blue curaçao. The cocktail is made by pouring all the ingredients into a shaker filled with ice. The mix is shaken and then strained into a martini glass and garnished with a lemon twist.
Lemon juice is sometimes also included. The cocktail is typically garnished with a lime or lemon twist. The origin of Angelo Azzurro is not entirely clear, but its invention is mainly associated with Giovanni Pepè. The cocktail was first introduced in Rome sometime in the 1980s, but it became incredibly popular in the 1990s.
