Backstory
In the early 2010s, bartender Jeffrey Morgenthaler of Clyde Common in Portland, Oregon, sought to redeem the Amaretto Sour from its reputation as an overly sweet drink made with sour mix. He deconstructed the classic, adding high-proof bourbon to balance the amaretto's sweetness and egg white for texture. His formula became an instant hit, transforming the drink's perception globally and establishing a new standard for modern sours.
Origin
Created by Jeffrey Morgenthaler around 2012 at the bar Clyde Common in Portland, Oregon, USA.
Improved Amaretto Sour

Ingredients
This recipe requires a quality amaretto, a potent cask-strength bourbon, and fresh lemon juice. Simple syrup adds a touch of sweetness, while egg white provides its iconic rich texture.
- Amaretto45 ml / 1.5 ozA quality amaretto like Luxardo or Lazzaroni is recommended.
- Cask-Strength Bourbon22.5 ml / 0.75 ozThe high proof is crucial for balancing the sweetness. Booker's or a similar high-ABV bourbon works well.
- Fresh Lemon Juice30 ml / 1 ozMust be freshly squeezed for best results.
- Simple Syrup (1:1)5 ml / 1 teaspoonAdjust to taste depending on the sweetness of your amaretto.
- Egg White15 ml / 0.5 ozCreates the signature velvety texture and foam. Pasteurized egg whites can be used for safety.
Ice type
- Cubed ice for shaking and one large cube or sphere for serving.
Mixing equipments
You will need a standard cocktail shaker set, including a jigger for measuring and two types of strainers to ensure a perfectly smooth and frothy final drink.
- Cocktail shaker for combining and chilling ingredients.
- Jigger for accurate measurement.
- Hawthorne strainer for straining from the shaker.
- Fine-mesh strainer for double straining to achieve a smooth foam.
Instructions
The key to this drink is the two-step shaking process: a dry shake without ice to build foam, followed by a wet shake with ice to chill and dilute. Double-straining ensures a silky-smooth texture before garnishing.
1. Add all ingredients—amaretto, bourbon, lemon juice, simple syrup, and egg white—to a cocktail shaker without ice.
2. Seal the shaker and perform a "dry shake" (shaking without ice) vigorously for about 15 seconds. This emulsifies the egg white and creates a rich foam.
3. Open the shaker, fill it with cubed ice, seal it again, and perform a "wet shake" for another 10-12 seconds until well-chilled.
4. Place a large ice cube in a chilled Old Fashioned glass. Double-strain the cocktail through both a Hawthorne and a fine-mesh strainer into the glass.
5. Express the oils from a lemon twist over the surface of the drink and drop it in. Garnish with one or two brandied cherries.
Garnishing
The cocktail is traditionally garnished with both a lemon twist, for its aromatic oils, and a rich brandied cherry, which complements the nutty flavors.
- Lemon twist: Express the oils over the drink's surface before dropping it in.
- Brandied cherry: Drop one or two high-quality brandied cherries into the finished cocktail.
