Muddle the nectarine slice in a shaker to release its juices and flavors.

Add the añejo rum, freshly squeezed lime juice, Cynar, and peach liqueur to the shaker.

Fill the shaker with ice and shake vigorously until well-chilled.

Double strain the mixture into a chilled martini glass, ensuring the nectarine pulp is thoroughly filtered out.
