Challah is an eggy yeast bread that's traditionally eaten by Jewish people on Shabbat and other holidays. Braided challah is the most common type.
Not only is challah a tasty kind of bread, it's also highly significant in Judaism. Having two loaves at a meal symbolizes the manna, or food, that fell from heaven when the Israelites wandered through the desert. A piece of dough set aside before baking represents a tithe, or religious contribution, and salting the challah is an important part of blessing the meal, as salt symbolizes an eternal bond with God.
