This is not the original Blue Moon recipe, this is a 1940s variation made by Crosby Gaige that is essentially a dry Aviation. The original recipe is from Hugo Ensslin’s Recipes for Mixed Drinks and is the same as the Yale Cocktail recipe included in this app, except that it used of Creme Yvette instead of Creme de Violette. I find the use of Creme Yvette interesting as its actually red in color not blue, and its odd that this variation was made in 1940s America, as Creme de Violette was not available in the United States then. Unfortunately these are oddities I do not have answers for.
