Actually most pasta's don't use yeast....they contain gluten, but not yeast. So most pasta's would be safe, I would think. Â Yeast is primarily used as a rising agent as far as I know. Someone please correct me if I'm wrong!

For baking you can use double the leavening agents and leave out the yeast. I make my own crackers for my son all the time and I never use yeast in them at all. Just mix whatever flour you want, some water, baking soda and whatever flavorings you want. Roll out thin, cut into pieces and bake until crispy.
