Muddle the Blueberries and Simple Syrup:

In a mixing glass, add about 8 fresh blueberries and the simple syrup.

Gently muddle the blueberries to release their juice and flavor, but be careful not to pulverize them into a complete mash.

Add Bourbon and Bitters:

Pour the bourbon and add two dashes of Angostura bitters to the mixing glass.

Stir the Mixture:

Add a few ice cubes to the glass.

Stir the mixture gently for about 30 seconds to combine the flavors while chilling the drink.

Strain into a Glass:

Strain the mixture into an Old Fashioned glass over a large ice cube to reduce dilution.

Garnish and Serve:

Garnish with an orange peel and a couple of fresh blueberries on a skewer or floating on top.

Optionally, give the orange peel a twist over the drink to release its oils before adding it to the glass.

Enjoy:

Enjoy your Blueberry Old Fashioned responsibly.
