Also known as a mezcalita, the mezcal margarita is a smoky variation on the classic.
Optional salt rim: Rub a lime wedge around the rim of the glass and then dip into a plate of salt.
In a shaker, mix the mezcal, orange liqueur, and lime juice with ice. Add agave nectar or simple syrup if you prefer a sweeter taste.
Shake until mixture is chilled.
Strain the cocktail into the prepared glass.
Garnish with a lime wedge.
