Sounds like your baking soda is old and/or spoiled. It explains the lack of rise, tingling tongue, chemical taste (washing soda [sodium carbonate, I think] is made by heating baking soda [sodium bicarbonate] in big ovens), and maybe the extra salty flavor, too. I’ve had bad baking soda spoil baked goods, and it’s a real bummer. Hope you try again, though.
Hello, I had similar problem (not as drastic) with my son. If the bread you are giving him is gluten free he is getting no gluten. Try putting a piece of cheese with a dab of honey on his plate and see if the picks it up eventually. Don’t mention anything different. Also a very thin slice of apple or banana with almond butter on it. Just Introduce different things but about the same size and coloring. Next He needs to be on a protein shake with hidden kale in it. You must start slow with almond milk and ice and honey. See if he will drink it with a straw? If you can continue adding other things– he will pick it up eventually. Also use behavior modification by telling him if he tries the shake ( one sip at first) you will let him watch a favorite show or movie. He likes these flavors already. Good Luck.
I wanted to try your recipe and I found almost all the ingredients here where I live. But I’m still stuck on the isolate whey protein. Could I skip to another protein, like pea protein? Do you think it alters rising/taste? I’ve never baked anything with this powder proteins, and since this pea protein happens to be the one easily on reach, I was wondering if you could help me sorting this out.
