Challah bread is a traditional Jewish egg bread. Most of the time it is a braided bread, but you don’t have to braid it. There are a lot of eggs in this bread, that provides two things. First, a fuller richer flavor, and second a longer shelf life. I have left this bread out for as long as a week. When I say out, I mean uncovered. The presence of the eggs also help giving the bread a golden brown color.
