Found this recipe on Tammy's Blog (http://www.tammysrecipes.com/homemade_vanilla_extract) and couldn't resist trying it. I made 3 batches; one with vodka, one with gluten-free vodka and one with bourbon. It'll be 6 months before they're totally mature, but I might have to test one out a little sooner. :) I purchased 1/2 lb of very fresh Madagascar Bourbon Vanilla Beans online for this recipe. The recipe is for 12 ozs of vanilla essence but it can be made in any amount needed. Just figure out how many ounces you want to make and add more vanilla beans in the same ratio.
