I think it depends on the flour. I've used brown rice and the texture was a little different. I have gotten used to it, though.
This time around I used a gf blend from bob's mill. Pretty pricey, though.
Isn't it all?!lol I tried making my own flour blend:
1/2 cup potato starch(not potato flour)
1/4 cup tapioca starch
2 tbsp. amaranth or millet flour
2 tbsp sorghum flour
I haven't tried it yet but it's ready to go for the next time I need flour.
