These two large words can be scary to read. But the common word for these words is yeast, a sugar-eating fungus.
Yeast is a single-celled fungi used to leaven bread. To grow, yeast digests its favorite food, sugar, in its various forms, granulated or brown sugar (sucrose); honey, molasses, maple syrup, fruit (fructose and glucose); and maltose in flour. As the yeast digests the sugar, it ferments to produce carbon dioxide (gas) and ethyl alcohol. The gas is trapped in the stretchy dough network and expands. The ethyl alcohol gives flavor and aroma to the bread.

That’s a fascinating explanation! I always wondered about the science behind bread rising. My first attempt at making sourdough failed miserably, and I suspect my yeast wasn’t active enough. I might try again soon. Maybe a good recipe will help. I wonder if anyone makes a simulator like they do for other recipes. I bet there’s even one for Eggy Car! That sounds like fun.
