There are many recipes for homemade vanilla extract. Basically, there are 3 ingredients – vanilla beans, vodka (or brandy, rum, bourbon, as long as it is at least 80 proof), and TIME.
The most important ingredient in the recipe is – TIME.
How I made mine?
I started in 2014. December.
With 1 liter of vodka and 14 Madagascar Bourbon vanilla beans.
I split the beans and scraped the seeds out. I placed all the seeds and pods into the bottle of vodka, capped the bottle, and then wrapped the bottle in brown paper. The bottle got named and tagged then into a cool cupboard it went… where it stayed for 3 years.
I opened it today and took a whiff.
