What It Is
Baking soda is just sodium bicarbonate. Although that sounds chemically and not quite like food, it’s actually a natural leavening agent that has been around for millennia (source). It can make a great addition to your Paleo baked goods to help you get that chewy texture you remember from baked treats when you were growing up.
Baking soda has many uses aside from getting the right texture in baked goods. It’s also effective at neutralizing odors, putting out fires, and cleaning everything from pots and pans to drains. You can also use it instead of toothpaste.
