Brain-Duster (William Schmidt)

Chill a cocktail coupe in advance to ensure it is ready to receive the cocktail.

Fill a shaker with ice and add the absinthe, sweet vermouth, Amontillado sherry, freshly squeezed lime juice, and simple syrup.

Shake the mixture vigorously to blend and chill the ingredients thoroughly.

Strain the cocktail into the prepared coupe, allowing the liquid to flow smoothly and leave any ice behind.

Serve immediately and enjoy the sophisticated balance of flavors.
