Noted for its beautiful color, this old-school gin Aviation cocktail is as blue as the sky. Created before Prohibition, this staple was lost to the United States after the Noble Experiment. Luckily, the return of lots of classic liqueurs and quality spirits put this cocktail back on the market.
Some notes on this recipe: This is a sweet drink when made with Creme de Yvette, and not blue or violet as pictured but pinkish. The Bitter Truth guys make a Creme de Violette, but when using lemon juice is a cloudy greyish color and is somewhat of a more bitter flavor profile overall as the spirit maker's name would suggest. Whatever you do don't use Drillaud's as it is just food coloring in sugar water. We tried several variations using different products and could not create this visually stunning drink in any way that tasted good.
I found a recipe for Aviation in a small book titled "Old Man Drinks." It didn't have the "creme de violette"; it called basically for equal parts of Maraschino liqueur & lemon juice with a couple ounces of gin. Of course it's not blue, but yellowish from the lemonade. Still: works for me!
