Nacho Sour

Rinse a chilled cocktail coupe with mezcal, ensuring to discard any excess.

In an empty shaker, combine the blanco tequila, Licor 43, freshly squeezed lime juice, lemon juice, rich simple syrup, bitters, and whisked egg white.

Dry shake the mixture to emulsify.

Add ice to the shaker and shake until thoroughly chilled.

Double strain the cocktail into the prepared coupe glass.

Garnish with a twist of lime peel.
