My riff on Maks Pazuniak's Warning Label from the 2011 Beta Cocktails book.
1 oz Plantation OFTD Rum
1 oz Lustau East India Solera Sherry (*)
1/2 oz Benedictine
1/2 oz Cynar
1 dash Mole Bitters
Campari for a glass rinse
Grapefruit twist for a garnish
Stir with ice, strain into a Campari-rinsed cocktail coupe, and garnish with a grapefruit twist.
(*) An Amontillado or Oloroso will work here in a pinch but will come across as a little drier and lacking light raisiny notes. Lustau's cream sherry is a mix of Oloroso with a little Pedro Ximenez.
