Description
Artisan and other yeast breads are made from dough prepared with yeast, which, over time leavens the dough, causing it to rise and become less dense. Yeast is a living organism: a one-celled fungus. Various strains of yeast are present virtually everywhere. Yeast feeds on carbohydrates present in the starches and sugars in bread dough, converting them to carbon dioxide and ethanol, an alcohol, in an organic process known as fermentation.
