Nightshade-Free Gluten-Free Flour Mix

This nightshade-free flour mix is perfect for gluten-free recipes of all sorts like GF bread, GF pancakes, cookies, and more. Nightshade-free basically means potato free as other nightshade veggies are not used in GF flour!

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. Here I provide you with a very simple nightshade-free gluten-free flour mix you can use in muffins, cakes, pizzas, bread, pancakes, and other gluten-free recipes.

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

Mixing flours in a large jar with a spoon.

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.


What Gluten-Free Flour Is Most Like All-Purpose Flour?

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).

Why Is There No Xanthan Gum In This Flour?

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.
