Put 6-7 ice cubes and 1 teaspoon of sugar in a shaker.
Add a tablespoon of amaretto liqueur and the espresso lungo.
Close the shaker well and shake vigorously for 10-15 seconds.
Open the shaker and pour it in a cocktail glass, removing the ice with the appropriate strainer.
Finally, add a few drops of slightly stirred liquid cream on the surface and sprinkle with bitter cocoa.
