Ingredients

The core ingredients for a Tequila Sour are tequila, fresh lime juice, and agave nectar. Egg white is optional but highly recommended for a classic frothy texture.
  • Blanco or Reposado Tequila60 ml / 2 oz
    A 100% agave tequila is recommended. Reposado will add subtle oak and vanilla notes.
  • Fresh Lime Juice30 ml / 1 oz
    Freshly squeezed juice is essential for the best flavor.
  • Agave Nectar15 ml / 0.5 oz
    Can be substituted with simple syrup (1:1 ratio). Adjust to taste.
  • Egg White15 ml / 0.5 oz (from one medium egg)(optional)
    Adds a rich, frothy texture. Can be substituted with aquafaba for a vegan version or omitted entirely.
  • Angostura Aromatic Bitters2-3 dashes(optional)
    Primarily used for garnish on top of the foam, which also adds a lovely aroma.

Ice type

  • Cubed (for shaking)

Mixing equipments

  • Cocktail shaker for mixing and chilling
  • Jigger or measuring cup for accurate pouring
  • Strainer for separating ice from the drink

Instructions

The key to a great Tequila Sour with a frothy head is the two-step shaking process: a dry shake without ice, followed by a wet shake with ice to chill and dilute.
1. Chill your serving glass (a coupe or rocks glass) by filling it with ice or placing it in the freezer.
2. Add tequila, lime juice, agave nectar, and egg white (if using) to a cocktail shaker without ice.
3. Perform a 'dry shake': seal the shaker and shake vigorously for about 15 seconds. This emulsifies the egg white and creates a rich foam.
4. Open the shaker, fill it with cubed ice, and seal it again.
5. Perform a 'wet shake': shake hard for another 10-15 seconds until the outside of the shaker is well-chilled.
6. Empty the ice from your chilled glass.
7. Double-strain the cocktail into the chilled glass to ensure a smooth texture.
8. Let the foam settle for a moment, then garnish by dotting a few drops of Angostura bitters on top.

Garnishing

The classic garnish is a few drops of Angostura bitters on the foam, which can be swirled for a decorative effect. A lime wheel or twist also works well.
  • Angostura bitters drops dropped onto the foam head
  • Lime wheel or twist as an alternative or additional garnish
