I used Kahlua instead of Galiano. (probably would have tried Mr. Black if I'd had some) But this is a very tequila-forward cocktail, which is surprising, as the other sherry cocktails I've tried are generally sherry-forward.
I'd say it's like you finished Tequila in a sherry cask. Probably would have a bit more coffee notes if I used Mr. Black.
What would the suggested type of rum be? Aged Jamaican? When I’m logged in it suggests Appleton when I’m logged out it suggest Bacardi 8 which are TOTALLY different rums.
