Add everything to a shaker without ice.

Dry shake hard for about 10–15 seconds.

Add ice and shake again until well chilled.

Double strain into a coupe glass or a rocks glass over a large ice cube.

Let the foam settle for a few seconds before garnishing.

Add 3-4 drops of Angostura onto the foam and drag a toothpick through them to make a little pattern.

Lastly, add a tiny dusting of pumpkin pie spice and a lemon wedge on the rim.
