Love this when I’m in the mood for rum. Perfect balance and looks really impressive when you serve it to guests.

Didn't have any Barbados rum so I used Appleton 8. It was good, but I'll reserve judgement until I've tried it with a few other rums.

Had this again today 30 October (U.S. National Candy Corn Day). Again it was perfect, but you must like rum being the forward taste and you must use a good rum. Incidentally, it does go excellently with Candy Corn.

I'm noticing that many Corn N Oil recipes elsewhere include lime juice as an ingredient - generally an amount equal to the Falernum.

I even found one recipe, claiming to be the more authentic version used in Barbados, that swapped the Falernum and Rum ratios - 1.5 oz Falernum, .5 oz Rum. Interestingly, the picture looked spot-on for the drink's namesake - clear on the bottom, and "oily" on top. Also called for the juice of two lime wedges on top.

Thoughts?

My first recipe was really disappointing. I used Bacardi 8, Plantation Dark rum for the float and my DIY Falernum liqueur (which is pretty good). I tried a second recipe and it was quite good (but not great): Plantation Barbados, Plantation OFTD 69% for the float, my DIY Falernum liqueur, 15 ml lime juice and 5 ml rich syrup (2:1). It is possible to make this cocktail better by changing the rum, so as Simon Difford said: your choice of ingredients! This cocktail can range from 1 star to 5 stars.

Had this on an unseasonably warm (77F/25C) March evening. Used a 151 Hamilton False Idol 151 float. Great cocktail and very refreshing. Key is to have a very good rum and falernum.

I had this in a rooftop bar in a hotel in Albuquerque that had been a hospital. I finally found a recipe book that had it and I can't remember its name, but it's somewhere in my library. If you know it, you could save me time. It's a pretty good and surprisingly named drink.

This is a great cocktail but I like some more lime than just a garnish, so add approx 15ml lime juice. I used gosling's as the dark rum as that's what I had.
