1 empty vanilla bottle
1 bottle of Vodka
1-2 Vanilla Beans
Split the vanilla bean on one side so that the top have is cut, being careful not to cut it all the way through. Place your bean(s) in the bottle and fill it with vodka. Shake the bottle once each day for 4 weeks.
It will then be ready to use. Each time you use your vanilla, top it off with vodka. Replace the vanilla beans every six months.
