I’m guessing it’s mostly ginger, plus maybe nutmeg, cinnamon and maybe cloves.
Also, on the subject of rum: is it just me, or could I make an absolute fortune by opening up my own rum distillery in, say, Haiti or Jamaica? I could pay the locals something like $3/hr and they’d think they were getting a king’s ransom. For the raw materials I’d need, what, maybe molasses, yeast, water & sugar? The biggest expenses would be bottling (plastic or glass) and the molasses. Could I use Grandma’s Sorghum Molasses® like I buy at Wal-Mart when I want to make oatmeal cookies? Or would I have to buy a more high-powered (and more expensive) pure sugar cane molasses?
I know that Sammy Hagar opened up a tequila distillery in Mexico, and he said on Behind the Music that he’s made tons more money as a distiller than he ever made in heavy metal.
