- oz Del Maguey Chichicapa mezcal
- oz simple syrup
- oz club soda
- oz egg white
- dashes Angostura bitters
Use an open flame from your gas stove (or kitchen torch, or broiler) and a pair of tongs to char a half a grapefruit, and a few additional slices for garnish. Juice the charred half-grapefruit. Pour the mezcal, grapefruit juice, simple syrup, egg white and bitters into an empty cocktail shaker. Dry shake, then shake with ice. Strain into a coupe, then top with club soda. Garnish with a charred grapefruit slice.
