So how did I find this out you ask? I was home alone with the girls this evening and wanted to make some "clean eating pumpkin bread" for a coffee date I am having tomorrow, but remembered I was out of baking powder...
So I thought to myself, Dale can stop at the 24 hour Sobeys on the way home and grab some. I will get everything ready and bake the bread in the morning. As I was messaging Dale and sending him a link of the aluminum free brand I use, I found this:
So, I made some. And my bread rose better than the last time I made it! It was only baking soda and cream of tartar. Both of which many people have on hand. So next time you are in a pinch or want to reduce your exposure to aluminum make your own.
