Amaretto Sour – Classic Almond Citrus Sour Cocktail

The Amaretto Sour is a smooth, citrus-forward cocktail that leans into comfort and simplicity. Built on the rich almond sweetness of amaretto and brightened with fresh lemon juice, this classic sour delivers an easy-drinking balance that’s stood the test of time.

Background

The Amaretto Sour gained popularity in the 1970s as Italian liqueurs like Disaronno entered the American market. It quickly became a go-to for drinkers who preferred sweeter, approachable cocktails. While modern versions have evolved, the original remains a nostalgic favorite rooted in simple sour cocktail structure.

What You’ll Need

Ingredients

• Amaretto – the sweet, nutty base that defines the drink
• Lemon juice – brings acidity and balance to the sweetness
• Simple syrup – optional sweetness adjustment for smoother balance
• Egg white – adds a creamy texture and stable foam

No simple syrup? Skip it entirely—the amaretto often provides enough sweetness on its own.

Equipment

• Shaker
• Strainer
• Whiskey sour glass

Sweet Meets Citrus

What makes this version stand out is its soft, dessert-like profile. Unlike sharper sour cocktails, the Amaretto Sour leans round and mellow, making it an easy entry point for new cocktail drinkers or anyone who prefers a smoother sip.

Substitutions & Variations

• Add a dash of bitters to cut sweetness slightly
• Swap lemon for lime for a sharper citrus edge
• Use flavored syrup (like vanilla) for a dessert-style twist

Helpful Tips

• Always use fresh lemon juice for the best flavor
• Shake thoroughly to properly chill and dilute the drink
• Dry shake first to properly emulsify the egg white and build foam
• Serve immediately for the freshest taste and texture
