Sourdough bread, as we call it today, was the first type of leavened bread humans discovered. Most likely, ancient Egyptians made this discovery—by accident. Traditionally, Egyptians baked flat, unleavened breads; according to historians, however, dough left out in the open sometimes underwent a transformation and, when baked, rose higher and tasted better than unleavened loaves.

Sourdough bread, as we call it today, was
the first type of leavened bread humans
discovered. Most likely, ancient Egyptians
made this discovery—by accident.
Traditionally, Egyptians baked flat,
unleavened breads; according to historians,
however, dough left out in the open
sometimes underwent a transformation and,
when baked, rose higher and tasted better
than unleavened loaves.

Bread
This mysterious transformation explains the
science behind sourdough bread. As dough
sits out, wild yeast spores from the air enter it
and feed on sugars in the flour. Over a few
hours or days, the yeast creates bubbles that
cause the dough to expand or rise and also
give it a tangy flavor.

Bread
Today, sourdough bread-bakers can still
create loaves without using commercial
yeast. By mixing a sourdough starter—which
might include flour, water, and sugar—and
nurturing it indefinitely, bakers can allow their
dough to ferment at room temperature with
the natural yeasts found in the air.
