Old fashioned cocktail

Method

1. Pour the bourbon whiskey into a heavy-based tumbler or old fashioned glass with 2 ice cubes. Stir for 10 seconds, then add the rye whiskey (or blended whisky), sugar syrup, a few dashes of Angostura bitters and a few more ice cubes and keep stirring.
2. Add more ice to fill the glass, then twist a pared piece of orange zest over the drink to catch the oils and drop it in the glass. Enjoy!
