Recipe Notes

Need a different amount?


Customize the amount you need with this simple recipe: Combine 1 part baking soda and 2 parts cream of tartar. That's it!


If you are making more than what you need for a recipe to store for later, add 1 part arrowroot flour to the mixture to help absorb moisture and keep it from activating. But this ingredient is completely optional if you don't want to add it. Store in an air-tight jar for up to one month. It loses its effect over time, so I suggest making it in smaller batches as you need it.


Single-Acting Baking Powder


Note that this is a single-acting baking powder. It reacts when liquid is added to it. So make sure your baking recipe gets to the oven as soon as it's mixed and ready.
