How to make your own baking powder - two versions!

Making your own baking powder is quick, easy, and it’s a great piece of knowledge to have tucked away. I can’t tell you how many times that knowing how to make it has saved me a trip to the store in the middle of making a recipes.

Another great reason for making your own, is that you know what is in it. People who have allergies to gluten or are following very strict grain-free guidelines know that most store-bought baking powders contain things like cornstarch or other starches.

Another questionable ingredient that anyone might want to avoid, no matter what your diet, is aluminum.

Aluminum is a neuro-toxin that studies have shown may lead to neurological disorders or cancers. Some studies have even linked it to Alzheimer’s disease. It is found in all sorts of things, including most deodorants.

I avoid aluminum as much as humanly possible and will not buy cookware or other kitchen items that have any sort of aluminum in it. It’s one of the reasons I love cast iron so much. I also use a natural, mineral based deodorant and have for years.

Not all store-bought baking powders contain aluminum, however, many or even most of them do. The only way to know for certain that it does not contain it, is to purchase baking powder that is specifically labeled as “aluminum free.”
