Whiskey Sour

Pro tips

• Shake vigorously with ice for 10–15 seconds to properly chill, dilute, and blend the sugar and lemon into the whiskey.
• Strain into a rocks glass over fresh ice; strained ice waters down the drink too quickly, but fresh ice keeps it cold longer.
• Use freshly squeezed lemon juice—bottled is noticeably inferior and will throw off the balance.
• Taste and adjust: if too sour, add a pinch more sugar; if too sweet, add more lemon juice or whiskey.

Substitutions

• Old Mr. Boston Whiskey → any bourbon, rye, or blended whiskey (brand and style will shift flavor slightly)
• Powdered Sugar → 1/2 tsp simple syrup or 1/4 tsp granulated sugar dissolved in a few drops of water

Storage & make-ahead

Whiskey sours are best served immediately after shaking. Pre-mixed cocktails without ice can be stored in the refrigerator for up to 24 hours, though flavor and dilution will fade.

What type of whiskey works best in a whiskey sour?

Bourbon, rye, blended, or Canadian whiskey all work well. Bourbon is the most traditional; rye adds spice; blended whiskey is smooth and approachable.

Can I use bottled lemon juice instead of fresh?

Fresh lemon juice is strongly preferred for bright, natural flavor. Bottled juice tastes flat and bitter by comparison.

Should I add an egg white to this whiskey sour?

The classic recipe shown uses only whiskey, lemon juice, and sugar. An optional egg white creates a silky foam top; use pasteurized eggs if adding.

How do I sweeten a whiskey sour if I don't have powdered sugar?

Dissolve regular granulated sugar in warm water to make simple syrup, then use 1/2 teaspoon. Powdered sugar dissolves faster when shaken.

Can I make whiskey sours in bulk ahead of time?

Mix the lemon juice and sugar base ahead; add whiskey and shake with ice just before serving for best flavor and dilution.
