1 oz aged rum
1 oz curaçao
0.5 oz lime juice
1 oz grapefruit juice
0.25 oz simple syrup
Build over ice in a chilled glass, top with soda water and stir briefly to combine.
The sip begins with a hit of grapefruit, segues into orange, rhum agricole, and lime, then finishes bittersweet-ly.
While not complicated, this was a very pleasant drink. I adjusted the recipe because, while I had grapefruit juice and soda water, I didn't have any grapefruit soda. I think the improvisation worked just fine. But if you do have grapefruit soda around, drop the grapefruit juice and simple syrup. Also, while I used rhum agricole to give this one a bit of a kick, any kind of aged rum should do. Jamaican would be my next choice, but something from Barbados, St. Croix, or Puerto Rico will be even more mellow.
