Ingredients

The core ingredients are smoky mezcal, tart fresh lime juice, and sweet agave nectar. An optional egg white provides a signature silky foam and texture.
  • Mezcal60 ml / 2 oz
    An unaged (joven) mezcal works best to let the smoky agave flavor shine.
  • 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, but agave nectar complements the base spirit.
  • Egg White15 ml / 0.5 oz (about half of one large egg white)(optional)
    Adds a rich, silky texture and foam. For a vegan option, use 1 tablespoon of aquafaba.
  • Angostura Bitters2-3 dashes(optional)
    Primarily used for garnish on the foam, adding aromatic complexity.

Ice type

  • Cubed (for shaking), None or Large Cube (for serving)

Mixing equipments

You will need a standard cocktail shaker set, including a jigger for precise measurement and two types of strainers to achieve a smooth, foam-topped drink.
  • Cocktail shaker for mixing and chilling ingredients.
  • Jigger for accurately measuring liquids.
  • Hawthorne strainer and a fine-mesh strainer for double straining.

Instructions

The preparation involves a 'dry shake' without ice to create a rich foam, followed by a 'wet shake' with ice to chill and dilute. Double straining ensures a perfectly smooth texture.
1. Chill your coupe glass by filling it with ice or placing it in the freezer.
2. Add mezcal, lime juice, agave nectar, and egg white (if using) to a cocktail shaker without ice.
3. Perform a 'dry shake': close the shaker tightly and shake vigorously for about 15 seconds to emulsify the egg white and create foam.
4. Open the shaker, fill it with cubed ice, and close it again.
5. Perform a 'wet shake': shake hard for another 10-15 seconds until the outside of the shaker is well-chilled.
6. Discard the ice from your chilled glass. Double strain the cocktail through a Hawthorne strainer and a fine-mesh strainer into the glass.
7. Let the foam settle for a moment, then garnish with a lime wheel or a few dashes of Angostura bitters on the foam.

Garnishing

Garnish with a simple lime wheel or elevate the presentation by adding a few drops of Angostura bitters onto the foam head for visual appeal and aroma.
  • Lime wheel placed on the rim of the glass or floating on the foam.
  • Angostura bitters artfully dashed or swirled on top of the egg white foam.
