For bringing the daytime coffee culture into the dark side of the day, the combination of Espresso Martiki & biscuit flavor is a my highly-recommended recipe. People are able to enjoy the traditional dessert coffee pairing with this drink without any homemade ingredients, except for one shot of espresso. Dark rum and biscotti liquor are also suitable for the nightcap cocktail, enhancing the cold brew coffee flavor of Mr. Black, the best coffee liquor in the world.
Pour all the ingredients into the three pieces shaker.
Add ice cubes. 3cm*3cm*3cm size is prefer.
Shake well with smile.
