3 vanilla beans (I brought mine from Mauritius!)
1 cup vodka
and a bottle!
All you do is pour unflavored vodka into a glass bottle, split the vanilla beans in half and stick them into the bottle. A good ratio is 1 vanilla bean per 1/3 cup of vodka. You need to let this steep in a dark place at room temperature for a couple of months until it is ready to use.
Really easy! Christmas is in 6 months, so you can start making some nice gifts now and keep them in a dark (secret :)) place. Have fun!
