I found this recipe on thespruceeats.com.

Rum, oj, grenadine⁣
⁣
The recipe for this drink was originally published in 1934 in The Old Waldorf-Astoria Bar Book, in the “Cuban Concoctions” section. That’s all of the history I know about this drink, but in researching, I learned a tidbit about Cuban drinks in general…Cuba was a hot spot not only for American tourists who wanted to drink during Prohibition, but also for American bartenders who wanted to work. ⁣

At first glance, you might think you’re looking at a Cosmopolitan – but the similarity ends there. While Cosmos are VERY sweet and VERY sour, this drink is more mellow and allows the nice taste of the rum to come through. ⁣

Because there is so much rum in a Cuban Rose and so little oj and grenadine, I was afraid this was going to go down roughly, like my experience with martinis. Nope. I haven’t had enough rum drinks to know if it’s just the rum that goes down easily, or if that little bit of oj is enough to smooth out the taste. I can tell you this – if I want to drink (or serve) pretty pink cocktails in pretty glasses, I’ll choose this over a Cosmo, any day. ⁣
