Split vanilla beans down the center with a knife or scissors.
2 whole organic vanilla beans
Slip the beans into a recycled glass jar or a canning jar. Use a jar that holds two cups of liquid.
Pour vodka into jar and allow it to sit for three to four weeks.
2 cups vodka
Leave the vanilla bean in the jar and when your supply starts to get low, add more vodka. (Eventually, you may need to start fresh when the beans start to lose their oomph.)
Notes
As you use the vanilla, you can top off with more vodka.
