Black Jack Shot

Chill the shot glass by placing it in the freezer or filling it with ice and water, then set it aside.

Refrigerate both the black sambuca liqueur and Tennessee whiskey until thoroughly chilled.

Carefully layer the black sambuca liqueur into the chilled shot glass, ensuring a smooth pour.

Gently float the Tennessee whiskey on top of the sambuca by pouring it over the back of a spoon to create distinct layers.
