This is a great method passed down over generations and perfected using the Instant Pot.
Fill 5 - 8 oz mason jars with vodka and leave about 2 inches at the top.
Carefully slice 5 vanilla beans down the middle.
Place 1 sliced vanilla bean in each of the jars of vodka.
Place trivet in the bottom of your Instant Pot liner. I couldn't find my trivet this day, so I just crumbled up aluminum foil to place the jars on.
Add 1 cup of water to the bottom of your Instant Pot liner.
Place the lids on the mason jars loosely. I tighten them until I just feel a little resistance, then pull back just a bit. You don't want the jars to seal while they are in your Instant Pot.
Place the lid on your Instant Pot, close the valve, and set to manual high pressure for 30 minutes.
Allow your Instant Pot to natural release for at least 30 minutes, then carefully remove the jars from the pot using tongs or heat resistant oven mitts or gloves.
This is when I tighten the lids down and allow the lids to seal. You can wait until they cool to tighten them down if you don't want them to seal.
Use cheesecloth to strain the particles from the beans or you can just use it with the little pieces of bean in it (that's what I do). I like the extra vanilla flavor :)
