I have recently had a problem with rice. You know they have genetically altered rice, so it is not the same as we used to eat. I do not eat rice or rice flour.
I also cannot eat soy flour, tapioca flour or bean flours, or potato flour.
For baking I suggest you try various combinations of sorghum flour, almond flour, corn flour, coconut flour & cornmeal. I use coconut milk for baking.
Somehow after 4 years I have just adjusted to gluten-free baking from regular recipes. For a banana bread I would sub cup for cup with a cup of sorghum flour & then corn flour & then either some almond flour or coconut flour to fill in the amount of flour needed. It should also turn out okay with just sorghum flour & corn flour, add a little extra of the levening agent & about 1/2 teaspoon xanthan gum & it should turn out perfect.
I look for recipes that have plenty of eggs, fat, added dried fruit, apples, bananas, or other veggies like grated carrot. Those type of recipes are easy to convert.
I do not bake bread I just use corn bread. I just sub corn flour for the wheat flour in any recipe & do not use any xanthan gum, cornbread does not need it. you can also make it into corn muffins or fry little corn cakes. You can also make hush puppies, the recipe is a little different, all kids love hush puppies, there again just sub the corn flour for the wheat flour & do not add xanthan gum.
I also suggest white corn tortillas for your little one. heat them up in a skillet & then roll up with PB & jelly, add bacon or whatever else. anything is good rolled in a corn tortilla.
