Serving

The Amaretto Sour is served cold in an Old Fashioned (or rocks) glass, typically over a single large ice cube to minimize dilution. It has a moderate alcohol content, making it approachable yet satisfying.

Backstory

Originating in the 1970s in the USA, the Amaretto Sour initially capitalized on the popularity of Italian liqueurs but was often made with commercial sour mix. Its reputation suffered until bartender Jeffrey Morgenthaler reinvented it around 2011. By adding cask-strength bourbon, fresh lemon juice, and egg white, he created a balanced, complex version that restored the drink's prestige and made it a staple in modern cocktail bars.

Ingredients

This cocktail requires amaretto liqueur, bourbon, fresh lemon juice, simple syrup, and an egg white. Using high-quality spirits and fresh juice is key to achieving the perfect balance.
  • Amaretto45 ml / 1.5 oz
    A quality amaretto like Luxardo or Disaronno is recommended.
  • Bourbon22.5 ml / 0.75 oz
    A high-proof or cask-strength bourbon adds depth and cuts through the sweetness.
  • Lemon Juice30 ml / 1 oz
    Must be freshly squeezed for best results.
  • Simple Syrup5 ml / 1 teaspoon
    Adjust to taste depending on the sweetness of your amaretto.
  • Egg White15 ml / 0.5 oz(optional)
    Creates the signature foam. Can be substituted with aquafaba for a vegan version or omitted entirely.

Ice type

  • Cubed ice for shaking, one large cube or sphere for serving.

Mixing equipments

A cocktail shaker, jigger, and a set of strainers are essential tools for this drink. Double straining is recommended to ensure a silky-smooth texture free of ice chips.
  • Cocktail shaker for combining and chilling ingredients.
  • Jigger for accurate measurement of liquids.
  • Hawthorne strainer and a fine-mesh strainer for double straining.

Instructions

The preparation involves a 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 into a glass with fresh ice ensures a perfect serve.
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' vigorously for about 15 seconds. This emulsifies the egg white and creates a rich foam.
3. Open the shaker, fill it with cubed ice, and seal it again.
4. Perform a 'wet shake' by shaking hard for another 10-12 seconds until the outside of the shaker is well-chilled.
5. Double-strain the cocktail (using a Hawthorne strainer and a fine-mesh strainer) into a chilled Old Fashioned glass containing a large ice cube.
6. Express a lemon peel over the drink's surface, then add the peel and a cherry as a garnish.

Garnishing

Garnish with an expressed lemon twist for a bright, citrus aroma and a high-quality cherry for visual appeal. Some also add a few drops of Angostura bitters onto the foam for an aromatic garnish.
  • Lemon twist, expressed over the drink to release its oils.
  • Brandied or Luxardo Maraschino cherry.
