Challah assuredly is one of the most iconic of all Jewish foods. Challah is as much a ritual and tradition than it is a recipe. It has a whole array of things and equipment associated with it: challah covers, boards, trays, knives — though some traditions never use a knife on challah —, tins, cookbooks, prayers, initiation rituals, recipes and secrets... Challah is omnipresent in Israel and in the Jewish diaspora, especially in the United States where it became a staple in every deli, be it as the ultimate French toast or even in a kugel, a Jewish baked pudding, and present in every decent supermarket.
