QUOTE from THE RISE OF YEAST

"The sight of the rising dough must have seemed magical to the early bakers. It remains so today. Bakers faithful to unleavened bread must have discarded these deformities until someone with a sense of adventure decided to put them in the oven. This was nothing less than an act of culinary heroism, on par with the invention of ice-cream."
