Japanese Whisky Sour Recipe

Make 1:1 honey syrup

Combine 2 tbs honey and 2 tbs hot (not boiling) water in a small jar or bowl. Stir until the honey fully dissolves and the mixture is homogeneous. Let cool to room temperature. This yields roughly 1.25–1.5 oz of syrup—use 0.5 oz for the cocktail and reserve the rest for another drink.

Prepare glass

Chill a coupe or a rocks glass by placing it in the freezer for a few minutes or filling it with ice water while you mix the drink. If you prefer served on the rocks, have a large fresh ice cube ready.

Dry shake (no ice)

Into a cocktail shaker, add 2 oz Japanese whisky, 0.75 oz fresh yuzu juice, 0.5 oz honey syrup, 1 large egg white, and 1 dash Angostura bitters. Seal the shaker and shake vigorously without ice for about 15–20 seconds. The dry shake emulsifies the egg white and creates initial foam.

Wet shake (with ice)

Open the shaker, add about 1 cup of cubed ice, reseal, and shake hard for 12–15 seconds until the shaker is well chilled and the exterior is frosty. This chills and dilutes the cocktail and builds a silky foam.

Strain

Discard the ice/water from the chilled glass if you used it. Double-strain the cocktail (through the shaker strainer and a fine mesh strainer) into the chilled coupe or into the rocks glass over a large fresh ice cube, depending on your serving preference.

Top and decorate

Carefully add 1 dash Angostura bitters onto the foam. Use a toothpick or small skewer to drag the bitters into a simple pattern (three small dots or a spiral) if desired. Float a thin yuzu wheel or twist on the foam or rest it on the rim.

Serve immediately. The finished cocktail should have a silky, stable foam, bright yuzu acidity, gentle honey sweetness, and the signature softly spiced character of Japanese whisky.
