Q: I saw a recipe for bread that didn’t include sugar. Without sugar, what’s feeding the yeast?
While yeast do eat sugar, we forget that flour contains starch, which is made from sugar molecules.
Actually, the yeast doesn’t eat the sugar. It breaks down glucose molecules and releases carbon dioxide gas.
The crusty, artisan-style breads that many bakers prefer these days usually don’t have sugar. In fact, Ken Forkish’s new book on artisan bread and pizza is simply titled “Flour Water Salt Yeast.” That’s all you need.
