My wife just started a gluten-free diet, and out bread machine does not have any special settings. What needs to be adjusted for gluten-free mixes?
I do have machine with the gluten free setting, but have also successfully made bread with a gluten-free recipe on just the white bread setting and it came out fine. You can't over work gluten free dough, supposedly.
Try a search of this forum for more threads on gluten free bread baking. There is lots of great information on this site.
