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?
