The Whiskey Sour is the sour template applied to American whiskey: spirit, citrus, sugar, in balance. Documented since the 1860s, it predates most of the cocktail canon and remains the friendliest possible introduction to bourbon — bright, soft, and endlessly easy to drink.
Spirit, Citrus, Sugar
The formula is the same one behind the Daiquiri and the Margarita — only the spirit changes. Bourbon brings vanilla and corn-sweet roundness; fresh lemon brings the cut; simple syrup ties them together.
Use a bourbon with enough proof and backbone to stand up to the lemon. A drink built on a thin, low-proof whiskey will taste of lemonade with a vague warmth behind it.
The Egg White
The optional egg white is what separates a good Whiskey Sour from a memorable one. It adds no real flavour — what it adds is texture: a dense, ivory foam and a round, silken body.
The technique is a dry shake: shake the drink once without ice to whip the protein, then again with ice to chill and dilute. Strain over fresh ice or serve it up, and finish with a few drops of bitters on the foam.
