“The universe of bread is made up of a nostalgia for one’s childhood the hard work of farmers, miller and bakers and the distinctive pleasure given by something ‘authentic and flavorful.'”

Hydration is a measure, expressed as a baker’s percentage of how wet a dough is. The hydration includes all the flours in the dough, including any in preferments, and all the liquids and fats in the dough, including any in the preferments.

The actual amount of yeast is changed depending on the temperature where the poolish will be allowed to rise and how …
