Why Make Your Own Baking Powder?

Avoiding Additives – many baking powders contain sodium aluminum sulfate, which some people wish to avoid

Why Is There Aluminum in Baking Powder?

Some baking powders are made with an aluminum-based salt–sodium aluminum sulfate or sodium aluminum phosphate. These substances become acidic when heated.

Baking soda is basic and it reacts with an acid to make baked goods rise. So these aluminum salts are part of what makes your baking powder containing baked goods rise.

As I mentioned, it’s been debated whether or not this form of aluminum contributes to such diseases as Alzheimer’s, etc., but regardless, many people wish to avoid this ingredient.

Interestingly, some people claim that baking powder that contains sodium aluminum sulfate can result in baked goods having a metallic taste, however from my research, that doesn’t seem to be the case–they appear to be either tasting some kind of residue from their baking pan or what they are tasting is the result of too much baking soda.

So this aluminum-free baking powder is simply a baking powder that doesn’t contain sodium aluminum sulfate or any other aluminum-containing ingredient.

Does Baking Soda Contain Aluminum?

Contrary to some sources, baking soda does not contain aluminum, so if you see a product labeled “aluminum-free baking soda”, that is either a marketing ploy, or an uninformed company.

Why Corn-free Baking Powder?

Not only is this homemade baking powder an aluminum-free baking powder, but it’s also a corn-free baking powder. Most baking powder is made with cornstarch, but this one is not.

So it’s perfect for those avoiding corn due to allergies or intolerances, as well as those on a grain-free diet.

As it turns out, this recipe works for many special diets. It’s not only corn-free, but it also works for the paleo, AIP, and grain-free diets.

Why Is There Arrowroot in This Baking Powder Recipe?

Arrowroot helps absorb moisture and as such will extend the shelf life of the product. So you can make a larger batch and keep your baking powder longer.

If you plan on making smaller batches and using this homemade paleo baking powder up quickly, then you can eliminate the arrowroot or other starches.

Another option, if you’d like to make a larger batch but still address the moisture problem, is to add silic a packs to the baking powder after putting it in a container.

Keto Baking Powder Option

To make this baking powder starch-free and completely keto, just omit the starch. The recipe will likely not keep as long but it will work in recipes.

Recipe Notes and Substitutions

Alternative Starches: If need be, you can use organic tapioca flour / starch instead of arrowroot, or, if you are not avoiding corn, organic cornstarch is another option.
Starch-free Recipe: If you can’t have any starches, you can use this recipe without it. As mentioned above, the starch primarily helps to keep the other ingredients from reacting and so it prolongs the life of the baking powder.
