The one thing I learned is that gluten free all purpose flour is great but you have to add at least xanthan gum to it to keep it from crumbling. I make homemade drop biscuits with it and they just fell apart until I used the xantham gum. I get it at Walmart it is in a packet like yeast. There are lots and lots of diff ideas on how best to do gf baking. I am a scratch cook but still haven't figured out how to make bread from scratch. It is confusing to understand all the whys and wherefores I think. But if you take some time to research there are lots and lots of good ideas out there for recipes.
I started out by reading the Wheat Belly diet as some friends had gone on this and that was my starting point. I don't follow the diet strictly but it is good info as to what has gluten in it.
