Intriguing. The Maraschino and Lime almost clash but get away with it. I used Burnt Faith English Brandy which is pretty robust (in a good way) and it ended up being a complex drink without either bitters or an amaro in sight!
The flavors work surprisingly well together. The Maraschino is quite forward but the gin and cognac does a good job at reigning it in. I think it would work even better if you had a full flavoured gin and cognac just to make them even more noticeable. I don't think the added sugar is required though, or maybe reduce it to a couple of dashes.
This is quite delicious. Probably a little more appropriate for a summer evening versus the middle of February, but either way a grand way to start the weekend. All the flavours play well together, no one ingredient overwhelms the others.
