Did you know you can make baking powder? The benefit is no aluminum, which for a discerning pallet can be off-putting. Plus, who wants to eat aluminum?
1/4 cup cream of tarter
2 tablespoons baking soda
Sift all of the ingredients together a few times
Store in a tight-sealing jar, in a cool dark place. It only keeps for a couple of months, so don’t make too much at a time.
