This nightshade-free flour mix is basically a gluten-free flour mix without potato starch. It is perfect for gluten-free recipes of all sorts like gluten-free no-knead bread, American gluten-free pancakes, gluten-free sourdough discard cookies, dairy-free pork chop coating, and more.

It took me a while to learn the importance of combining various gluten-free flours to achieve the best texture and flavor in baked goods. Wheat and whole wheat breads are airy and beautiful as they are thanks to gluten, but we need to be creative to make up for the loss of that magic ingredient!

What Foods Are Nightshade?
Nightshade food is a group of vegetables that include tomatoes, eggplant, peppers, and potatoes. Potato starch and/or flour are very frequently used in gluten-free flour blends which makes it hard for people allergic to nightshade veggies to use.
What Is A Good Substitute For Potato Starch?
My go-to is cornstarch! When I need more chewiness in a recipe, like in cassava flour pizza, for example, I use some tapioca starch as well. You can use arrowroot starch if it is available to you but I find it hard to get a hold of!
I recommend substituting potato starch for any other starch 1:1 as starches behave very similarly in gluten-free recipes.

How To Make Nightshade-Free GF Flour

Mix all the flours in a large mixing bowl until well incorporated and store in an air-tight container or a glass jar! The flour will last several months at room temperature.
FAQ
A ratio of 70% flour/30% starch is the best for a gluten-free flour blend to make it as close as possible to all-purpose flour. So, if you want to make 1kg of GF flour, use 700g of your favorite gluten-free flour (whole grain is better) and 300g of starch (cornstarch, tapioca, and/or arrowroot starches).
I intentionally don't add a binder to my flour mix because different recipes call for different amounts/types of binders. For example, in my gluten-free sandwich bread, I like to use psyllium husk powder, while for GF American-style pancakes I will use xanthan gum.

Natasha, what do you suggest to substitute for both of the rice flours. Should I, or can I use 2 different flours?
Natasha Levai says
Hi Vicki! You can use sorghum flour in place of brown rice flour and yes, millet flour will work in place of rice flour!
