Separately, use a hand blender or dry shake to lightly whip and combine heavy cream and vanilla salt, then set aside.
Add ice to mixing glass, stir gently to chill and lightly dilute, then pour contents into a chilled pousse-caf? glass.
Using the back of a bar spoon, float the vanilla salted cream over the top of the drink, then garnish with additional vanilla salt.
