Place the chopped apple pieces and honey syrup into the bottom of a cocktail shaker.

Muddle firmly until the apple releases its juices.

Add the bourbon, fresh lemon juice, and a generous amount of ice to the shaker.

Cover and shake vigorously for fifteen seconds until well chilled.

Strain the liquid over fresh ice into a double rocks glass.

Garnish with an apple slice and serve immediately.

Combine the honey and warm water in a small jar or glass measuring cup.

Stir vigorously until the honey completely dissolves into the water.

Allow the mixture to cool to room temperature before using.

Store any leftovers in an airtight glass container in the refrigerator for up to one month.
