Kosher USA follows the fascinating journey of kosher food through the modern industrial food system. It recounts how iconic products such as Coca-Cola and Jell-O tried to become kosher; the contentious debates among rabbis over the incorporation of modern science into Jewish law; how Manischewitz wine became the first kosher product to win over non-Jewish consumers (principally African Americans); the techniques used by Orthodox rabbinical organizations to embed kosher requirements into food manufacturing; and the difficulties encountered by kosher meat and other kosher foods that fell outside the American culinary consensus.
