2 Vanilla Beans
1/2 C Vodka (or Ever Clear)
The higher the alcohol content in the Vodka, the better the extraction so purchase a Vodka that is 100 proof or better. You can also use Everclear for maximum extraction.
Cut each vanilla bean in half and then split each one length-wise to maximize exposure to the beans nesting inside. Slide into bottle. Warm the alcohol to 140° and cover beans. Place the lid on the bottle and let set for approximately 6 weeks - shaking it occasionally. There is no need to open the bottle until after the 6 week period.
At this point, you can remove the vanilla beans (if you want) and enjoy your own high quality vanilla!
