Sloe Gin Sour

The Sloe Gin Sour is a classic cocktail that offers a delightful twist on the more common Whiskey or Gin Sour. It uses sloe gin, a British liqueur made from gin and sloe drupes, which imparts a unique plummy and berry-like flavor. This fruitiness is perfectly balanced by the sharp tartness of fresh lemon juice and a touch of sweetness. When made with an optional egg white, it develops a rich, silky texture and a beautiful frothy head, elevating the drinking experience.

Ice type

  • Cubed

Mixing equipments

This is a shaken cocktail requiring a standard cocktail shaker set. Double straining is recommended if using egg white to ensure a perfectly smooth foam.
  • Cocktail shaker for combining and chilling ingredients.
  • Jigger for accurate measurement.
  • Hawthorne and fine mesh strainers for a smooth, ice-free drink.

Instructions

The key steps involve a two-part shaking process: a dry shake without ice to build foam, followed by a wet shake with ice to chill and dilute. The drink is then double-strained into a chilled glass and garnished.
1. Chill your coupe glass by filling it with ice or placing it in the freezer.
2. Combine sloe gin, fresh lemon juice, simple syrup, and egg white (if using) in a cocktail shaker without ice.
3. Perform a "dry shake" by sealing the shaker and shaking vigorously for about 15 seconds to emulsify the egg white.
4. Add a generous amount of cubed ice to the shaker, seal it again, and perform a "wet shake" for another 10-15 seconds until the outside of the shaker is frosty.
5. Empty the ice from your chilled glass. Double strain the cocktail through a Hawthorne and fine mesh strainer into the glass.
6. Garnish with a lemon twist expressed over the surface of the drink.

Garnishing

A simple lemon twist is the classic garnish, adding a bright citrus aroma that complements the drink's flavors. Alternatively, a brandied cherry can be used.
  • Lemon Twist: Express the oils over the drink's surface before dropping it in.
