Chill an absinthe glass to prepare for serving.

Stir the dry vermouth, Bénédictine, and absinthe in a mixing glass filled with ice until well-chilled.

Strain the mixture into the chilled absinthe glass.

Garnish with an orange twist.

Consider experimenting with blanc vermouth. As noted by Meehan, many classic recipes like the Algonquin, El Presidente, and Blackthorn, which traditionally use dry vermouth, may have enhanced flavors when blanc vermouth is used.
