Cool the coffee before mixing. Make sure to cool the coffee completely before shaking it with the other ingredients for a nice chilled cocktail.
To get the nice layer of foam, shake vigorously. You will need to create the foam yourself by shaking it in the cocktail shaker.
Sift the cocktail quickly. When pouring the cocktail into the glass, make sure to do it in one pour to ensure the foam ends up on top.
To create a simple syrup. Simply boil a 1:1 ratio of sugar to water until the sugar has dissolved. Turn off the heat and store it in the refrigerator. Make sure it is completely cooled before using.
