Add a few ice cubes and the absinthe to a double rocks glass.
Stir a few times, liberally splashing the sides of the glass.
Tilt the glass so the absinthe reaches the rim and turn slowly to coat the entire glass.
Discard the ice and excess absinthe, and set aside.
Add the remaining ingredients to a shaker and fill with ice.
Shake well and pour (unstrained) into the prepared glass.
Garnish with lemon twist.
