Corn 'n' Oil requires that the rum be Black Strap rum. No other style other than black rum will do! This is a grave error in propagating correct cocktail information.

Grave error is mentioning Black Strap rum, as such a thing does not exist! Cruzan, a second class rum producer, uses this in its advertising.
Graver, even stupid, is putting comments based on advertisement influence rather than knowlegde!

Also nice if old genever substituted by young genever and a drop of tobasco added.
