Every batch of homemade falernum (almost always falernum #9) is validated via a Corn and Oil. Don’t accept any Corn and Oil recipe that calls for blackstrap rum - they’re reading too much into the word “oil”. This is a Barbados cocktail, and should be assembled accordingly.

Corn And Oil (Smuggler’s Cove version)

1/2 oz falernum - homemade here, but the SC recipe calls for Taylor’s Velvet Falernum

2 oz blended, aged Barbados rum (Planation 5 in this case)

2 - 4 dashes of Angostura bitters (4)

Add everything to an old-fashioned glass and add crushed ice to almost fill. Stir/swizzle until frosty. Sip.
