There isn't that much you can do when it comes to baking soda substitutes. It really depends on what you are making. I am a baker myself and have had to make a different product since i can not drive to the store yet. My best answer is to just ask a neighbor or go to the store and buy it since lots of recipes call for baking soda. I hope that helped!
