I've got a small bottle with vanilla beans in it, just top it off with cheap vodka when it gets down a little. Probably Grain Alcohol would do fine, too, but I'm cheap.
Replace the Beans every few months, when I think of it. They cost a couple bucks for a small packet at World Market.
Saves money, and frankly, I like it better. I use it all the time for things like pancakes. Works just fine.
My wife makes her own ketchup and basil salt. I love the basil salt. She dries out the basil leaves from our plant and then grinds them in a food processesor with kosher salt. Man I like that seasoning... Like I needed an excuse to eat more salt :(
