Gluten free flour blend
You can also buy pre-made blends at the store. I haven’t in a while and there are a lot more options now. If it were me, I’d try the King Arthur gluten free flour blend.
Gluten free flour blend:
2 cups rice flour
1/2 cup sorghum flour
1 cup potato starch
4 tablespoons tapioca starch
2 tsp xanthum gum
2 tsp baking powder
