  1. 1

    Chill the Glass

    Start by chilling your glass. You can do this by filling it with ice water and setting it aside while you prepare the cocktail.

    In a mixing glass, combine the bourbon or rye whiskey, simple syrup, and Angostura bitters. Add ice and stir gently for about 20-30 seconds until well chilled.

    Prepare the Glass

    Discard the ice water from your chilled glass and strain the mixed cocktail into the glass over fresh ice cubes.

    Express the oils from the orange peel over the drink by holding it over the glass and giving it a gentle twist. Then, drop the peel into the glass. Finally, add a maraschino cherry for garnish.
