  • 0.5 ounces 15 ml agave nectar, or simple syrup as a substitute
  • 1 large egg white from a room-temperature egg
  • 2 dashes Angostura bitters optional but recommended
  • Pinch of smoked sea salt or fleur de sel for rimming optional
  • 1 lime wheel for garnish
  • Fresh high-quality ice cubes

Equipment

  • Hawthorne strainer
  • Fine mesh strainer
  • Coupe glass
  • Rocks glass

Method
 

  1. Chill a coupe or rocks glass in the freezer for at least 2 minutes before starting.
  2. Measure and pour 2 ounces mezcal, 0.75 ounces fresh lime juice, and 0.5 ounces agave nectar into the cocktail shaker.
  3. Crack and add 1 large egg white into the shaker, ensuring no yolk is included.
  4. Seal the shaker and perform a dry shake for 10 to 15 seconds to build the egg white foam.
  5. Add fresh ice to the shaker, reseal, and shake vigorously for another 10 to 15 seconds until the shaker is very cold.
  6. Double strain the mixture into the chilled glass using a Hawthorne strainer and a fine mesh strainer to remove any ice shards.
  7. Add 2 dashes of Angostura bitters on top of the foam, if using.
  8. Garnish with a lime wheel on the rim or floated on the foam and serve immediately.

Notes

Serve immediately while the drink is cold and the foam is still prominent.
