- Gather all ingredients and chill your serving glass.
- Measure 2 ounces of whiskey, 1 ounce of fresh lemon juice, and 1 teaspoon of sugar (or toasted sugar).
- If using an egg white, add it to the cocktail shaker with the lemon juice and sugar.
- Perform a 'dry shake' (shake vigorously without ice) for 15-20 seconds to emulsify the egg white, if using.
- Add the whiskey and ice to the shaker.
- Shake vigorously for 10-15 seconds until well-chilled.
- Strain the mixture into the chilled Old Fashioned glass filled with fresh ice.
- Garnish with a lemon twist or a cherry, if desired.
- Serve immediately and enjoy.
Notes
1. Always use freshly squeezed lemon juice; bottled juice will not yield the same vibrant flavor.2. For a Boston Sour (with egg white), a 'dry shake' (shaking without ice) first, then a 'wet shake' (with ice), is crucial for achieving a stable, silky foam.3. Consider using a good quality bourbon or rye whiskey for a more complex flavor profile.4. Toasted sugar adds a subtle caramel note that deepens the drink's character.5. Chill your serving glass beforehand for an optimal drinking experience.
