Aviation

The Missing Ingredient

Most drinks do not have a missing ingredient story. The Aviation does. Hugo Ensslin published the original recipe in 1916 with four components: gin, maraschino liqueur, crème de violette, and fresh lemon juice. The crème de violette is what gives the drink its colour, its name, and its defining character. It is also the ingredient that disappeared from virtually every subsequent published version of the recipe for most of the twentieth century.

The reason was supply rather than preference. Crème de violette, a liqueur made from violet flowers, became increasingly difficult to source in the United States and United Kingdom as the decades passed. Bartenders making the Aviation without it produced a serviceable gin and maraschino sour that retained the structure of the original but lost its identity. The pale lavender colour was gone. The floral dimension was gone. What remained was a good drink that happened to share a name with a great one.

When Rothman and Winter relaunched their crème de violette for the American market in 2007 the cocktail community treated it as a restoration rather than a novelty. The ingredient had been missing. Now it was back. The Aviation could be made correctly again.

Hugo Ensslin

Hugo Ensslin was head bartender at the Hotel Wallick in New York and published Recipes for Mixed Drinks in 1916, the last significant American cocktail manual before Prohibition closed the bars and interrupted the tradition. The book is a relatively modest document compared to Jerry Thomas's earlier work but it contains several recipes, including the Aviation and the Corpse Reviver variations, that have become cornerstones of the modern classic cocktail revival.

Ensslin was working in a specific moment in American cocktail history, the final years before Prohibition, when the craft was at a peak of sophistication and the bars of New York were producing work that would not be matched again until the late twentieth century. The Aviation is a product of that moment: precise, ingredient-led, and built around a component that required genuine effort to source even then.

Crème de Violette

Crème de violette is a liqueur made from violet flowers, producing a spirit with a distinctive floral character and a natural lavender colour that transfers directly into any drink it touches. It is sweet but not heavily so, and the floral note it carries is delicate enough to be lost if it is overpowered by other ingredients.

In the Aviation it appears at 15ml, the smallest measure in the recipe. That proportion is deliberate. The crème de violette is not the lead ingredient. It is the element that gives the drink its identity: the colour, the name, and the floral lift that sits above the maraschino and the lemon in the aromatic profile. Too much and it dominates aggressively and the drink turns an unappetising grey. Too little and it is lost. The 15ml measure is where the balance lives.

Rothman and Winter is the most widely available quality producer. Giffard also produce a crème de violette that works well. The colour and intensity of the violet character varies between producers, so the 15ml measure may need minor adjustment depending on which bottle you are using. Taste before serving on the first attempt.

Maraschino

Maraschino liqueur appears in the Aviation for the same reason it appears in the Last Word: it provides cherry sweetness and a faint bitter almond note that bridges other ingredients without duplicating them. In the Aviation it is sitting between the floral violet and the tart lemon, providing a sweetness that softens the citrus and a complexity that gives the violet something to work alongside.

Luxardo is the standard producer and the correct choice for the same reasons it is correct in the Last Word. Drier and more complex than generic alternatives, with the bitter almond note clearly present. In a recipe with only four ingredients the quality of each one is directly audible in the finished drink.

The Colour

The Aviation's colour is not a gimmick. It is the drink's most immediate communication of what it contains and what it is. A correctly made Aviation, with the right measure of crème de violette and the right measure of lemon, produces a pale lavender that sits somewhere between blue and grey. Hold it up to light and it looks like early morning sky. That is why it is named what it is.

The colour is also a balance indicator. If the drink is too blue or too purple the crème de violette measure is too high. If the colour is barely present the measure is too low or the lemon juice has overwhelmed it. A correctly balanced Aviation is pale and luminous, not deeply coloured. The subtlety is the point.

The Version Without Violette

The Aviation without crème de violette is a gin sour with maraschino. It is a good drink. It is not the Aviation. The distinction matters because ordering or making the Aviation without the violet and calling it the Aviation is like making a Bijou without the Chartreuse and calling it the Bijou. You have the structure but not the identity.

If crème de violette is unavailable, make a gin and maraschino sour and call it what it is. Do not call it an Aviation. Ensslin included the violet for a reason and that reason is present in every glass that contains it.
