Well, I made another today. It's a bit sweet for my tastes, but you can reduce the liqueurs by 5ml each and increase the gin by 10ml if you want. Personally, I like the sweetness. (Also, my palette is very dry, so it's not sweet compared to something like a Cosmo.)
60ml Gin (Gunpowder)
40ml Fino Sherry
20ml Honey Liqueur
20ml Gamondi Amaro
I might update this later based on more experimentation, but I like this one for now. Also, if you don't have Gamondi, I suggest mixing 10ml Averna and 10ml Montenegro----using Ramazzotti + Nonino and CioCiaro + Cynar might work also.
