The Twice Baked Bread of War

Zwieback is a sweet bread that was originally invented as an indestructible ration for mercenary soldiers. Because it is baked twice, it becomes incredibly crisp and stays fresh for a very long time.

During the brutal Thirty Years War, a general named Albrecht von Wallenstein needed a food source that could survive long military campaigns. By baking bread twice, he created a durable, shelf-stable snack that wouldn't spoil in the field. Eventually, this practical military ration evolved into the beloved household treat eaten across Europe today. It serves as a fascinating example of how battlefield innovation can become a global kitchen staple.
