Instead, she divides the background into the usage of yeast/baking of bread in chapter one and the usage of early chemical leaveners/baking of cakes and other baked goods in chapter two. And yet, the real genius in her division comes from the fact that, despite the chronological overlaps in these two background chapters and their themes, Civitello incorporates differing chronology into the chapter narratives, having chapter one focus more on earlier European bread baking, brought to the Americas by settlers, and chapter two focus more on American usage of early chemical leaveners in cakes and other baked goods.
