What is Kosher? What Makes foods Kosher?
Kosher in the Jewish religion means foods which are acceptable according to Jewish dietary laws. There are many laws in the Old Testament relating to permitted and forbidden foods and ways in which these may be prepared, and the sages who interpreted these laws, added several of their own, known as Rabbinic Laws, which are binding, if not quite as strict as the Torah Law itself. It is, despite this seeming to be a common myth..nothing to do with food being blessed by the rabbi or not. The only foodstuff to which a blessing is relevant is wine and the sabbath loaves. And these are blessed by the head of the household not a rabbi.
