Split the vanilla bean pods by slicing lengthwise. Scrape out the flecks of seeds into the jar (I love the seeds in my baking!)
Place the vanilla bean pods into the jar (tall jar is best so they fit, if not just cut in half).
Pour the vodka into the jar, place the lid on top and let sit in the back of your cupboard for at least 6 months!
I like to add 4-5 vanilla bean pods for every 8 ounces of liquid. You can also try out using rum, brandy, or bourbon instead of vodka. Just make sure that the alcohol isn't flavored!
