Funny. I have heard Alton Brown talk about it too. I have never tried it myself, least that I know of.
There's a great online spice store Wicked Wahine told me about where you can buy it. Call her back here!! She didn't say anything!!!
She knows stuff and she's holding out!! hehe
If you try it, let us know!! Also thank Wicked Wahine, she may have other web sites to share.
