Making your own real vanilla extract is simple. Buy the cheapest vodka you can find. Pour it into a mason jar. Add 6-8 vanilla beans, sliced open and chopped up. Put a lid on it. Store it in a cool, dark location for 8 weeks. Shake it every now and then. Strain into a new jar when you're ready to use and add more vodka to the beans in the old jar. Whenever you use a bean for another recipe, toss the remains into your extract jar. It will store indefinitely if kept properly.
