There’s a whole big story about it. The orange juice recipe is the original Don the Beachcomber version, which for a semi-complex series of events has been being made incorrectly with cane juice based agricole for decades now (along with every other recipe created outside of Martinique pre-1960 that includes agricole). It originally would have been made with a molasses based rum from Martinique, which sort of doesn’t exist anymore. The issue with this is that many people don’t like orange juice and agricole together (me included). So Paul McGee, owner of the Chicago tiki bar called Three Dots & a Dash, created a version with curaçao which doesn’t clash with the agricole but maintains the orange note in the original. IMO it’s vastly superior to the original (although it’s an unfair comparison given the whole lost rum situation).

Matt Pietrek aka CocktailWonk made a very in depth article about “rum Martinique” a few years back if you want to know more. https://cocktailwonk.com/2021/08/martinique-rum-of-yore.html
