Sometimes it seems like the allergies in my household just keep piling on us. In the past few years, my youngest has not outgrown any allergies, my oldest has re-developed her reactions to eggs, my husband has been hit with the oral-allergy-syndrome reactions, and I've developed an intolerance to yeast and a diagnosis of eosinophilic esophagitis from exposure to as-yet-uncertain foods. I usually try not to think about it all so that my head doesn't spin! But I've really been missing pizza and focaccia dough lately. Now that my Gram's go-to dough starter, Hot Roll Mix, doesn't have dairy (which was our issue there for years), I would love to try it again...but I've stopped using live yeast in our house. I'm a science researcher at heart, though, so I headed online and learned all about yeast alternatives: baking soda and baking powder, specifically. I was excited pretty much immediately, when I found out that baking powder came into existence because of A FOOD ALLERGY! In the 1800s! A British chemist's wife was allergic to eggs and yeast, so he standardized a powdered ingredient that she could use instead in her baking. A food allergy changed the world. :-) We've gotta love that, right? If you want to learn more, check out my entire post at
