0.75 oz lightly aged Rhum Agricole
0.5 oz high ester Jamaican rum (Smith & Cross ideally)
1 oz sweet vermouth (one of the rare instances I think Carpano makes sense in cocktails)
5/8 oz Campari
3/8 oz Tempus Fugit banana liqueur (no subs on this one)
2 dashes Bittermans Tiki bitters
Orange peel over the top and into the glass as garnish, bonus points if you flame it (usually not a fan, but it works here). I usually like to build this over one large cube so the first few sips are full strength and really funky / fruity before it mellows out into crushable goodness.
The x/8 measurements are finicky, sure, but I found it was the best balance with the r(h)ums and vermouth I used. Depending on what you use might require some tweaking
