Alcohol (vodka or bourbon)
Glass bottle or a Jar with an airtight cover
Slice the vanilla beans and place them in the glass bottle or jar
Pour a cup of alcohol of your choice (vodka and bourbon are most effective). Vanilla beans should be a quarter to full or fully soaked.
Shake the mixture in the bottle or jar once or twice a week for good sitting.
Wait for 6-8 weeks is your extract is ready for use.
If you want a strong flavor, leave the extract to sit for 6 to 12 months because the longer is sits, the stronger flavor.
