I've been trying to bake cornbread with brown rice flour instead of white flour and it comes out crumby. The whole thing is just a pile of crumbs. I think it's the absence of gluten that is not giving it any density/ allowing it to hold together. When I use white flour it comes out great! However, I'm trying to eliminate wheat/gluten from my diet. Is there something else I can use or a magic ingredient I can add to make it all come together?
