The first publication of this drink is in 1916 in Hugo R. Ensslin’s Recipes for Mixed Drinks. It is also featured in Harry Craddock’s book but in this he omits the crème de violette. Since then there has always been discussion whether the crème de violette should be there. If we think about it’s first debut in publication the aviation most probably was named after the rockstars of the time aviators. As cocktails have often reflected what was in vogue at the time this doesn’t seem any different. Potentially the crème de violette could be mirroring the blue sky.
