Bottle of bourbon or vodka
2 vanilla beans
Instructions: Cut the beans in half and drop into bottle of vodka/bourbon. Leave to set indefinitely.
As time passes the color of the bean soaks into the liquid, giving it a pretty golden brown color. The more surface area on your beans, the better. I scraped out my seeds for use in another project... perhaps ice cream or custard. I love custard.
My cost for this extract was around $0.33 / oz. Compared to real (not imitation!) vanilla extract, it is a great deal. Plus I have heard that you can keep filling the bottle up without replacing the beans, which are the costly part of this project.
And when I open the bottle, it smells like vanilla ice cream!
Happy extracting! (vanilla, not teeth...)
