I found an online source for Xanthan gum (8 oz. for $10.10, don't know if that is good price or not) and other hard-to-find dry foods. I've not ordered from them yet but since someone here was recently asking about sources for the Xanthan gum, thought I'd pass it along. Check out http://www.amescompany.com/online.htm There are all kinds of interesting things here. Deb in Houston
