Mix all ingredients with the ice cubes in the shaker. Abseil into a small glass.
Who also wants something to look at:
Shake all ingredients except the grenadine syrup with the ice cubes. Pour the grenadine syrup into the glass and carefully rappel down the cocktail so that a pink-red bar forms at the bottom.
A little hint:
Most shakers have a sieve on top, which allows the liquid part of the cocktail to be separated from the cream foam. This is how a beautiful hood can be conjured up on the cocktail.
