Homemade vanilla extract is truly in a different league than what can be procured from most grocery stores. The difference between pure vanilla and imitation vanilla is simple. Pure vanilla extract is made from vanilla beans, while imitation vanilla utilizes imitation flavors and chemicals.
Place beans in bottle and cover with vodka.If necessary you may bend the beans to fit into the glass jar.
Then put the lid on them, give it a few shakes, and then store in a cool, dark place. Leave it there for 2 months, while giving it a few shakes 2 days a week for the next 2 months. The LONGER it sits in the jar the BETTER.
