Invention of the bread oven
Culinary historians credit the Greeks for developing bread baking into an art. Front-loaded bread ovens were developed in ancient Greece. The Greeks created a wide variety of doughs, loaf shapes, and styles of serving bread with other foods. Baking developed as a trade and profession as bread increasingly was prepared outside of the family home by specially trained workers to be sold to the public. This is one of the oldest forms of professional food processing.
