The Atty Cocktail

History

Adapted from a recipe in Harry Craddock's 1930 The Savoy Cocktail Book.

ATTY COCKTAIL
¼ French Vermouth.
3 Dashes Absinthe.
¾ Gin.
3 Dashes Crème de Violette.
Shake well and strain into cocktail glass.

Harry Craddock, 1930

Many of the recipes in Craddock's 1930 book are borrowed from Hugo-R-Ensslin's 1917 Recipes For Mixed Drinks (the last major pre-Prohibition cocktail book) and, while there is no Atty cocktail, there is a cocktail called "Attention" in Ensslin's book which shares the same ingredients, listed in the same order, as the Atty but in misbalanced (equal parts) proportions:

ATTENTION COCKTAIL
¼ French vermouth
¼ Absinthe
¼ Gin
¼ Crème de Violette
Shake well in a mixing glass with cracked ice, strain and serve.

Hugo R. Ensslin, 1917

Due to the similarities, many have concluded that Ensslin's Attention inspired Craddock's rather better, perhaps abbreviated, Atty cocktail.
