My neighbor warned me that "you will find any thin spots in your oven mitts when you use a Dutch oven to bake sourdough at 450!" That's why I got the gloves. I already KNOW my mitts have thin spots.
GF flour is expensive, so I'm starting to grind my own. I used my Blendtec blender on short grain brown rice; it's a bit gritty. I have a juicer that has a grinding attachment, and that ground it a bit finer, though it still has more texture than store bought. Long grain white rice did a little better yet.
I want to try making oat flour and quinoa flour. And maybe tapioca. All the GF SD recipes call for a few different flours. I need to find some sorghum flour; that's a common one in GF. I went to the health food store I usually go to, and nada. I looked it up online, and guess who says they have it! Walmart!
@musikfan, what do you use to grind your flour? Can you post a picture too? Thanks!
