Okay, but it might benefit from some tweaks depending on one's preferences. I found it sweeter than expected, but with some spicy/bitter heat. The orange bitter essence seemed overly strong--I used Regan's, but the Calisaya has some orange bitter of its own and there is a lot of Calisaya in this, especially with the orange peel expressed and dropped into glass. Subbing Angostura Aromatic or another aromatic bitter might broaden the flavor. Or one might choose to back off on the Calisaya and/or vermouth to ~1/2 oz each and up the rye accordingly (e.g. 2 : 1/2 : 1/2.) I would rate the drink ~2.5 as is, but will bump it to 3 on the assumption that some tweaks would make it rotation worthy.

In all fairness to the originator of this cocktail, I have not had much success with the historical Calisaya recipes either, and am still looking for a compelling one. This recipe has some similarities to the "Good Fellow" from 1914 Straub and 1937 UKBG (50:50 Bourbon/sweet vermouth with dash each of Calisaya and Angostura.)

Made with Salers... which is not as bitter as suze and less vegetal / dirty. I think it would have benefited from the suze but still tasty.

This is an amazing cocktail. I'd been trying many different recipes with mezcal & passion fruit, but the crème de cacao balances it in a way that no other variation I've tried manages. I did not have Scrappy's firewater, so I substituted Bitter End mole bitters, which are quite spicy. I toasted to the memory of my pittie mix Loki and to Jack ❤️
