Glad you like the bitters! We agree that with gin as a base it’s a bit of a challenge, but you’ll love them with rum!
It got me thinking that I, in fact, had had a rum based cocktail with the Mole bitters at Death & Company a while ago. It’s no surprise that so many of the cocktails I like Bittermens bitters in are from Death & Co – they’re one of the few bars that had early distribution of them prior to release. I remembered ordering it because it had Ron Zapaca 23 year, a rum that at the time I hadn’t had but had heard great things about. Unfortunately I couldn’t remember the name of the drink.
I was conveniently poking around Bittermens website and lo! I found it! The cocktail is a Sazerac variation, created by Joaquín Simó.
2 oz Ron Zacapa 23 year old Rum
1/2 Bar Spoon Sugar Cane Syrup
1 Dash Angostura Bitters
1 Dash Xocolatl Mole Bitters
3 Dashes Peychaud Bitters
Absinthe, Herbsaint or Ricard
Fill a double old fashioned glass with ice and a small amount of Absinthe, Herbsaint or Ricard. Stir the Rum, Sugar Cane Syrup and bitters in an ice filled shaker glass. Dump the ice from the old fashioned glass and rotate the glass to ensure that the rinse coats the entire inside of the glass. Strain into the glass. Twist lemon peel over the glass and discard (do not put the twist in the glass).
I haven’t made this for myself yet, but it’s a great cocktail from what I remember and from the looks of it, my memory is serving me well.
[Post updated to reflect that Ron Zapaca 23 is not, in fact, a 23 year old rum.]
