Ancient Egypt’s bakers discover leavened bread using wild yeast
Leavened bread likely emerged in Egyptian kitchens around 4000 B.C.E., when dough left sitting on a warm day caught wild yeast and rose into something lighter and more flavorful than anything before it. Bakers couldn’t explain it, but they saved a piece of each batch and passed the living culture forward — a quiet craft that would feed civilizations for the next six thousand years.
