A shaken sour riff on the White Negroni, this drink adds lemon juice, sugar syrup, and egg white to navy-strength gin, Blanc Quinquina, and a gentian liqueur. A plush, cloud-like foam gives way to a bittersweet, herbal core, with bracing citrus cutting through the high-proof warmth on a long, dry finish.
The White Negroni Sour is a modern twist that reworks the White Negroni into a sour format, adding citrus and egg white to a drink that itself emerged as a pale variation on the Negroni, swapping Campari and sweet vermouth for gentian liqueur and blanc quinquina or vermouth to keep the bitter, herbal backbone while lightening the color and flavor profile.
The Negroni itself is widely traced to Florence, Italy, in the early 20th century, when Count Camillo Negroni is said to have asked a bartender at Caffè Casoni to strengthen his Americano by replacing the soda water with gin, creating the equal-parts gin, vermouth, and Campari drink that bears his name; the exact year and some details of that story are debated among historians.
A White Negroni is a bittersweet gin cocktail built from navy strength gin, Blanc Quinquina, and a gentian liqueur, and this version is shaken into a sour with lemon juice and egg white for a frothy, citrusy finish.
A Negroni is equal parts gin, a red bitter such as Campari, and sweet vermouth, giving it a deep red color and bold bitter-orange flavor. A White Negroni replaces the Campari with a gentian liqueur and the sweet vermouth with Blanc Quinquina, producing a pale, drier, more floral drink with the same gin backbone.
A Negroni is stirred and served short over ice with no citrus, while a Negroni Sour adds lemon juice, sugar syrup, and egg white and is shaken to a silky, foam-topped drink. This White Negroni Sour applies that same sour treatment to the White Negroni's gin, Blanc Quinquina, and gentian liqueur base rather than to Campari and sweet vermouth.
Shake navy-strength gin, Blanc Quinquina, a gentian liqueur, fresh lemon juice, sugar syrup, and egg white hard with ice, then strain into an ice-filled old-fashioned glass. Finish by expressing a lemon twist over the top and dropping it in as garnish.
Suze is one example of a gentian liqueur; other gentian liqueurs such as Salers or Bonal can be used in its place, as this recipe's ingredient list allows. Each brings the same bittersweet, root-forward character, though the exact bitterness and sweetness level will shift slightly depending on the bottle.
