Corn 'N Oil
3 oz Cruzan Blackstrap Rum (any blackstrap or dark rum will work, but for this application, I think Cruzan's tastes the best. Yes, I've tried several others)
1 oz falernum
juice of 1/2 lime
build over ice, stirring briskly to combine.
It really looks intimidating, but a sniff and a taste will set you at ease. This is easily one of my favorite drinks, just because of all the spiciness going on in it, between the dark molasses character of the rum and the spice cupboard appeal of the falernum. I love this one.
