Challah is a traditional Jewish bread that is made before sundown each Friday for the Sabbath meal. Most women will make two loaves so that there is enough to eat on Saturday (Sabbath) as well. The reason being is because the Jews don't believe in doing ANY kind of work from sundown Friday until sundown Saturday. That includes cooking, turning on a light, cleaning, shopping, etc. All foods are prepared in advance so no work is done. Challah is one of the highlights of Sabbath. It is also traditionally eaten with honey or honey butter.
