Gather all your ingredients and equipment.

If you don’t have simple syrup ready, combine equal parts sugar and water in a saucepan. Heat gently until the sugar dissolves and set it aside to cool.

Fill your shaker with ice.

Using a jigger, measure and add 2 oz of bourbon, 1 oz of fresh lemon juice, and 1 oz of simple syrup to the shaker.

Add 2 dashes of Angostura bitters to the mixture.

Secure the shaker lid and shake vigorously for about 15 seconds.

Use a strainer to pour the mixture into your prepared glasses filled with fresh ice.

Finish with a fresh lemon twist for garnish.
