Ingredients

2 ½ cups strong brewed coffee
4 cups sugar
2 cups white rum
1 vanilla bean

Instructions

If your 2 ½ cups strong brewed coffee is cold, heat it up in the microwave until hot. Mix t4 cups sugar into the hot coffee - set aside to cool. The sugar may not completely dissolve, that's ok. Set the coffee aside to cool.
Meanwhile, prepare your sous vide water bath. I used a large pot, and fill with hot tap water. Set circulator to 135f.
Slice t1 vanilla bean in half lengthwise, and cut into enough sections for the number of jars you're using. (I used 3 500ml jars). Place one section of the vanilla bean into each jar.
Once the coffee has cooled, add 2 cups white rum and mix well to combine. Divide the coffee, sugar, rum mixture between your jars. Leaving 1 inch of headspace in each jar.
Place lids on jars and spin the lids on finger-tight. Air needs to escape the jars while in the sous vide bath so not too tight!
Place jars into sous vide bath and cook at 135f for 3 hours.
Remove jars from the water bath and place them on a cooling rack to cool to room temperature before straining out the vanilla bean.

Notes

Substitutions

RUM: You can certainly swap out the rum, but I have only tested it with white rum. Dark or amber rum would be a quick and easy substitution.

SUGAR: This recipe could also be made with brown sugar, it would add more caramel flavor to the Kahlua.

storage information

A long time. Like pretty much indefinitely - if it lasts that long! To be on the safe side, I'd say around a year

There's no need to keep this homemade Kahlua in the fridge. This easy-going recipe can be stored in a cool, dark liquor cabinet.

instant pot with sous vide function

Follow all the same directions, BUT place your jar(s) on the trivet inside your Instant Pot. This keeps them off the hot base and allows water to circulate more freely around the jars during the infusion process.
