For every cup of vodka or bourbon, use 4 vanilla beans
4 vanilla beans (per), 1 cup vodka or bourbon
Cut each vanilla bean down the middle to access the insides. Put them in an air-tight container with a screw on lid (I use mason jars), and put in a sunny window for a week. Shake daily.
After a week is up, transfer to a cool dark location like a pantry or closet. Shake every few days to help distribute the vanilla flavor and to activate the infusing action.
The vanilla will be ready when the liquor has turned very dark and smells strongly of vanilla and not alcohol.
How to Make Instant Pot Vanilla Extract
Chop the vanilla beans in half, place in an 8 oz or pint canning jar. Add vodka. Add the lid and ring and tighten to fingertip tight.
Place 1 cup of water in the Instant Pot and place a wire rack inside. Add the jars.
Put the lid on the Instant Pot, set the vent to “sealing” and press Manual>high pressure>30 minutes.
Allow for a natural release. Carefully remove the hot jars from the Instant Pot and place on a towel to fully cool. Store in a cool dry place.
Notes
To gift, distribute amongst smaller bottles, and put a fun label on it. Do not strain or filter the vanilla; part of the magic of homemade vanilla extract is the little flecks of vanilla bean that infuses itself in your cooking.
