Prepare low ball glass with a large ice cube. Add whiskey, bitters, and sugar to a mixing glass filled with ice and stir for 20-30 seconds. Strain into prepared glass.
Slice off the orange peel, twist over glass to release some of the oils, and place the orange peel on top of the ice cube.
Start with quality ingredients: Use a high-quality rye whiskey or bourbon as the base for your Old Fashioned. Look for a whiskey with rich flavors and a smooth finish.
Sweeten it just right: Traditional Old Fashioned cocktails are sweetened with a sugar cube or simple syrup. For this version, I used brown sugar for an additional layer of depth. You could also consider using maple syrup, honey, or agave syrup.
Ice matters: Choose a large ice cube or a sphere to chill your cocktail. The larger ice melts slower, preventing the drink from becoming diluted too quickly. It also adds an elegant touch to the presentation.
Stir it properly: Stirring the cocktail properly is key to achieving a well-balanced drink. Use a long cocktail spoon and stir gently, allowing the flavors to blend together. Stir for about 20-30 seconds, or until the drink is properly chilled and dilute.
Garnish thoughtfully: Consider garnishing your black walnut Old Fashioned with an orange twist. Express the oils from the orange peel over the glass, then rub the peel around the rim before dropping it into the drink. This adds a delightful aroma and a touch of citrusy brightness.
