Prep Glass: Fill a coupe glass with ice and give it a quick stir. Set it aside.
Add Egg White (optional): Crack open 1 egg, separate white from yolk and pour the white into the shaker. Discard the yolk.
Add Bitters: Pour 2 dashes of Orange Bitters into the shaker.
Add Sugar & Agave Syrup: Add ¼ oz simple syrup and ½ oz agave syrup.
Add Lemon & Lime Juices: Measure and pour ½ oz lime juice & ½ oz lemon juice into the shaker.
Add Tequila & Rum: Finally, add 1 oz Blanco Tequila and 1 oz Dark Caribbean Rum to the mix.
Dry Shake (only if using egg white): Close the shaker and shake vigorously, without ice, for about 15-20 seconds. If you’re not using egg white, skip this step and go to step 8.
Shake with Ice: Open the shaker and fill it with ice cubes. Close the shaker and shake another time, for 10-15 seconds this time.
Strain: Discard the ice inside the coupe glass. Using both the cocktail strainer and the fine strainer, pour the drink into the chilled glass.
Garnish: Express a lemon peel on top of the drink and use another for garnish. Serve immediately.
