Is allergy to baking powder possible?
I posted 2 weeks ago about a reaction to an unknown contaminant while eating homemade pancakes. I decided that perhaps my son was allergic to cinnamon as all the other ingredients were quite basic and things he eats all the time (flour, brown sugar etc) and this recipe called for quite a bit of cinnamon. Anyhow, I made the same pancakes today but left out the cinnamon. He ate one then asked for a second one, and then he said , my tongue is itchy and it's that white stuff that bothers me. Other than the "itchy tongue" he reported there was no blotchiness on his face like the other time. Has anyone ever heard of an allergy to baking powder or did he just eat a little lump of it and hate the bitter taste? As recipes go it did call for a lot of baking powder-1 tablespoon.
