So I know that “Bourbon vanilla extract” doesn’t refer to using actual bourbon– it’s referring to vanilla beans from the Bourbon island of Madagascar– but I like bourbon and I like vanilla, so why not combine the two to make an amped-up version of vanilla extract?
The problem is that vanilla beans have skyrocketed in price over the last few years– six or seven years ago I bought a half-pound of beautiful, plump beans for a reasonably low price, and it lasted me ages, but now that I’m in the market for more it was a lot harder to find any reasonably-priced beans. I finally found a source on eBay, but they did give fair warning that the beans are pretty dry and not good for much besides making extract. They turned out exactly as described– thin, shriveled, and dry– and I certainly wouldn’t use these in baking since there’s not much “vanilla caviar” inside at all, but they’re fine for my purposes now.
Vanilla extract really couldn’t be easier to make– you just split your beans in half and plunk them into a bottle of your favorite spirit. Like I said, I like bourbon, and for a 750 ml bottle I used about twenty of these extremely dry, tiny beans. I think with better-quality beans you could use about 10-15 instead.
Anyway, I’ll let these soak for about 3 months before I start using the extract. In my experience you can just leave the beans in there, though some people like to remove them and strain out any bits at the bottom of the bottle. I read that you can pour off the extract into a new bottle and just re-use the beans, maybe adding in some new ones and taking out any particularly soggy ones, for a whole new batch– I may try it eventually.
