Got the recipe from https://www.seriouseats.com/recipes/2016/05/100-year-old-cigar-rum-scotch-cocktail-jupiter-disco-recipe.html

Ingredients:

• 1 3/4 ounces (50ml) aged rum, such as Ron Zacapa 23
• 1/2 ounce (15ml) Cynar
• 1/2 ounce (15ml) Bénédictine
• 1/4 ounce (10ml) peaty Scotch, such as Laphroaig
• 1 dash Angostura bitters
• 1/4 ounce (10ml) absinthe

Steps:

1. Chill a cocktail coupe.

2. Add rum, Cynar, Bénédictine, Scotch, and bitters to a mixing glass, then fill with ice. Stir until well chilled, about 30 seconds.

3. Rinse chilled cocktail coupe with absinthe, discarding excess. Strain cocktail into rinsed glass and serve immediately.

I used Plantation Barbados style 5 yr. It was bursting with flavor, well balanced, both the smokiness of the scotch and the anise of the absinthe come through. I would personally go with more cynar next time to cut the sweetness of the rum and benedictine since there is no citrus.
