Cut a piece of orange peel using a vegetable peeler.
Clean up the edges using a sharp paring knife, and then cut a slit in the center of the piece where it will sit on the rim of the serving glass. Set aside.
Cocktail
Add the white rum, orange juice, lime juice and simple syrup to a cocktail shaker.
Fill the shaker with ice.
Seal up the shaker and shake vigorously, about 15-20 times.
Strain the drink into the serving glass.
Attach the orange peel garnish to the rim of the glass and serve. Cheers!
Notes
If you want even more orange flavor, try using a little extra orange juice. Or, you could add in a few drops of orange bitters.
Although freshly squeezed juice is best, you can certainly use bottled juice in a pinch.
