Split the vanilla bean in half. You can use a sharp knife or a pair of scissors.
Add the split beans to the bottle.
Pour the vodka over the vanilla beans.
Put the lid on the bottle, and store for a few weeks. Give the bottle a shake every few days.
3 weeks later, you have a deep, dark, vanilla extract.
Pour the vanilla into smaller bottles (a funnel is helpful), add a label and a bow, and you have a perfect holiday gift.
