Ok, my dad is a celiac (meaning he is highly allergic to gluten) but before he found out, he absolutely loved good bread. I was thinking that a nice Christmas present might be to develop a sourdough starter that is gluten free that he could use in his home baking. He uses all sorts of flour in his bread (soy, brown rice, corn) but I don't know which one would be best for developing the starter or if I would need to do a combination. He normally uses a bread machine to make his bread. I'm kind of a luddite when it comes to bread. Can you make a decent sourdough in a bread machine?

If anyone has any idea about this or if you just want to tell me that it won't work no matter how hard I try, tell me.
