Comfortably Plum

Chill an Old Fashioned Glass in advance.

Combine the bourbon, shochu, umeshu, simple syrup, and bitters in a mixing glass filled with ice.

Stir the mixture until well-chilled and properly diluted.

Strain the cocktail into the prepared coupe glass.

Add a large ice cube to the glass.

Express the orange peel over the drink to release its oils, then add the twist to the glass.

Finish by sprinkling a pinch of salt over the ice.
