Zwieback is a form of very crispy toast which is often served to babies and invalids because it is easy to digest. This bread typically includes eggs, adding nutritional value to the loaf, and it is often sweetened to make it more palatable. Many markets carry zwieback, and it can also be easily made at home. Most classically, zwieback is eaten plain, although some people like to dip it in soups or warmed milk
