Not just wheat free, but they must have:
No almond or nut flours
No teff flour
Minimal rice flours (dd is mildly allergic, we limit)
Minimal tapioca flour
No dairy, though I can substitute butter easily enough
No xanthum gum or similar additives
These are OK:
Hoping for gingerbread dough (sturdy enough for a house?) but someone in another thread mentioned sugar cookies, and those would be fun, too.
I'd also want to minimize the ultra-fine zero-nutrient ingredients like tapioca and potato starch. I realize these might be necessary to make the dough rollable and crisp, but the recipes I'm finding are mainly rice flour/potato starch/tapioca starch and that sounds a might scary. I mean, these don't need to be bastions of nutrition and health, but something less thoroughly refined would be nice.
