Mixed-up Flours

The first time I tried to make scones with a GF flour mix the dough smelled like salty beans. I looked at the ingredients on the store-bought package only to find - sure enough - garbanzo bean flour. After trying a few other pre-made mixes with similarly disastrous results, I decided I could do better on my own. Over the last year or two I've been experimenting with making my own gluten-free flour mixes. While I'm not quite ready to share this secret concoction with the world, I do want share what I've learned about the properties of some basic gluten-free flours. Brown rice flour: It gives your product lots of texture and flavor. However, it is not pliable enough to be used by itself in most recipes, and it produces a dense, heavy, whole-grain feel.

White rice flour: This gives you a somewhat lighter and more pliable dough than brown rice flour, but without the benefit of the flavor of the whole grain. It is made from raw white rice.

Glutinous rice flour (or sticky rice flour): This flour does not contain gluten! The term is only meant to convey the gluey texture the flour has when wet. It is to be distinguished from white rice flour in that it is made from cooked white rice.

Potato flour and potato starch: This is the one flour that changed my mix the most. Bob's Red Mill says it best when they say it "lends a moist crumb." It also improves the elasticity of your dough quite a bit.

Tapioca starch: This flour is instrumental in getting your product to brown when cooked. You don't need to use a lot to reap its benefits, but if you use too much the dough will be gluey and dense.

Sorghum: This flour improved the taste of my flour mixes immensely. It has a sweet, nutty flavor. Use too much, however, and the dough will be wet and sticky.

Xanthan gum: This is not a flour but a gluten substitute. It is absolutely necessary for making your dough elastic.

These are the basic flours you will need to make all your gluten-free fantasies come true. Stay tuned - next week you can get my take on flours for more specialized purposes.

Nice breakdown, Gina. There's something about using a mix that just doesn't feel right--I mean, I took home economics, I can use a measuring cup. Ok, I didn't really take home economics, but still.

I'm continually surprised by how bad the mixes are - even from brands that I normally trust. It makes it hard. I just want something that I can scoop out for a recipe and sub 1:1 for wheat flour. I'm getting close to that with my own mixes.

Also, it would be interesting to hear what your least favorite flours are in another post. I have had success using oat flour to replace wheat flour for a couple recipes: apple crisp and peanut butter bars. It would probably work for brownies, too, as long as there's really not too much flour called for in the recipe.

It did NOT work for zucchini bread. I added some oat flour, baked the bread for HOURS, and it never cooked! I had to throw the whole thing away. I think the recipe was just too liquidy and the oat flour couldn't bind it.

By the way, I know oat flour is not usually 100% gluten free because oats are often processed with wheat. Bob's Red Mill (a local mill available nationwide, I think) does make a gluten-free oat flour.

Rebecca,

I do not often use oat flour. It is simply too gooey! I have tried your GF crisps with oat flour which were delicious, but when I add it to a flour mix for baking anything cakey or breadlike it makes the dough much too moist. Another post will be forthcoming for "specialty" flours!

Thanks for the tips! I tried adding the potato flour to my mix and you were right - it improved the texture immensely. Elasticity and moistness were greatly improved.
