Pickwick Club

Add the pineapple rum and overproof rum to an Double Old Fashioned Glass.

Introduce the passion fruit syrup, vanilla syrup, and Allspice Dram to the mix.

Add both the Angostura bitters and Bittermens Xocolatl Mole bitters.

Drop in the absinthe to round out the flavors.

Gently stir to combine and chill.

Add a large ice cube to the glass to keep the cocktail cold and slightly dilute.

Express the oils from an orange peel over the drink for a fragrant finish, then use the peel as a garnish.
