The cocktail known as 'The Aviation' was first created in the early 1900s at the Wallick Hotel of New York, by a gentleman named Hugo Ensslin. Mr. Ensslin first published this recipe in his own book, called 'Recipes for Mixed Drinks, in 1916. The creme de violet adds a slight sky blue color which perhaps inspired the name of this drink, in honor of the new aviation industry, just starting to emerge at this early time. A robust cocktail, not for the faint of heart. Wildly popular in it's day. Cheers!
